Your first day in IT is a blur of badge photos, password resets for accounts you didn’t know you had, and the slow, creeping realization that nobody around you seems to know what’s going on either. They’re just better at hiding it. I walked into my first IT job thinking I was behind, thinking everyone else had some secret manual I’d missed, thinking I was about to get exposed as a fraud before lunch. Spoiler: none of that happened. What did happen was years of learning things the hard way that somebody could have told me in about ten minutes. So consider this your ten minutes.
Nobody Expects You to Know Everything (Seriously, Nobody)
This is the big one. The one that would have saved me approximately forty seven stress stomachaches in my first year. You were not hired because they thought you were a walking encyclopedia of every protocol, platform, and PowerShell command in existence. You were hired because they saw potential and they needed a body in that chair. That’s it. That’s the whole thing.
The senior engineers around you? They Google stuff constantly. The guy who’s been there twelve years and seems like he built the network with his bare hands? He has a folder of bookmarked Stack Overflow threads that would make your head spin. The difference between a junior person and a senior person isn’t that the senior person has memorized everything. It’s that the senior person knows what to search for and how to filter the garbage results from the useful ones. That skill takes time. Give yourself that time.
Your First IT Certification Matters More Than You Think
I didn’t get my first cert until way too late. I thought experience alone would carry me. And sure, experience matters. But when you’re sitting across from an HR person who doesn’t know the difference between a switch and a router (and I say that with love, because I used to be that HR person), a certification is the shorthand that gets your resume past the pile and into the “maybe” stack.
You don’t need ten certs. You don’t need five. LinkedIn will try to convince you otherwise, but one well chosen certification early on can change your trajectory. If you’re brand new, something like the CompTIA A+ or an entry level security cert gives you structure. It forces you to actually learn the fundamentals instead of just absorbing random tribal knowledge from whoever happens to sit next to you. And if you’re not sure where to start, I wrote a whole breakdown on getting IT certifications with no experience that’ll save you some spiraling.
Document Everything Like Your Job Depends on It (Because It Might)
On day one, nobody tells you this. They hand you a laptop, point you at a wiki that hasn’t been updated since the Obama administration, and say “good luck.” So you fumble through things. You fix something. You move on. And three months later, the same problem comes back, and you cannot for the life of you remember what you did.
Start a personal notes file on day one. I don’t care if it’s a text file on your desktop, a OneNote notebook, or a composition notebook you write in with a pen like it’s 1997. Every time you solve a problem, write down what broke, what you did, and what fixed it. I promise you, six months from now, you will look at those notes like they were written by a genius. A disorganized genius, maybe, but a genius nonetheless.
The other reason to document everything? When something goes wrong and fingers start pointing, notes are your alibi. “I followed the process documented here, at this time, with this result.” That sentence has saved more careers than any certification ever has.
Asking Questions Doesn’t Make You Look Dumb
You know what makes you look dumb? Nodding along in a meeting, pretending you understand what “BGP peering” means, then quietly breaking something because you were too embarrassed to ask. That makes you look dumb. Asking the question up front? That makes you look like someone who wants to get it right.
There is a secret that experienced IT people won’t admit out loud: they love explaining things. Most of them got into this field because they’re obsessive about how things work. Give them an excuse to talk about DNS for twenty minutes and watch their eyes light up. You’re not bothering them. You’re giving them a stage.
Now, there’s nuance here. Google it first. Make an attempt. Then ask. “I looked into this and I think it’s X, but I’m not sure about Y” will get you a much warmer reception than “what’s a subnet?” when the answer is on the first page of any search engine. Show your work. Teachers love that. IT mentors love it too.
The Soft Skills Will Outrun the Hard Skills Eventually
I spent my early IT years thinking that technical ability was the only thing that mattered. If I could fix the thing faster than the other person, I won. Career advancement was basically a speed run of troubleshooting tickets. Right?
Wrong. So, so wrong.
The people who moved up fastest weren’t always the most technical. They were the ones who could explain a technical problem to a non-technical person without making them feel stupid. They were the ones who could sit in a meeting, translate the business need into a technical plan, and make both sides feel heard. The Bureau of Labor Statistics projects computer and IT occupations growing about 6% through 2033, and the people filling those senior roles aren’t just technically sharp. They can communicate. They can write an email that doesn’t read like a robot having a panic attack.
Practice writing clear, concise updates. Practice explaining things simply. This will pay dividends you can’t see right now.
You Will Break Something and That’s Fine
Not “might.” Will. You will bring down a service, delete something you shouldn’t have, push a change that cascades into chaos, or accidentally reply all to an email thread with something deeply unfortunate. It’s coming. Accept it now so it doesn’t destroy you later.
The measure of an IT professional is not whether they break things. It’s how they respond when things break. Do you panic and hide? Or do you escalate, communicate, and start working the problem? According to NIST’s Cybersecurity Framework, incident response is literally a formalized discipline. Entire careers are built around the fact that things break and someone needs to respond well. You’re not failing when you break something. You’re just getting early practice in a skill that will matter forever.
Also, if a single person’s mistake can take down production with no safety net, that’s not a “you” problem. That’s an architecture problem. Remember that when the post-mortem meeting gets tense.
Your Career Path Won’t Be a Straight Line
I went from IT to HR to sales and then back into the IT world. That path makes zero sense on paper. It makes complete sense in hindsight. Every detour taught me something that the “correct” path never would have.
You might start on the help desk and end up in cloud engineering. You might start in networking and realize you actually love security. You might get really into project management and wonder why you ever wanted to touch a server in the first place. All of that is fine. The IT field is enormous, and your first role is not your last role. It’s not even your second role. It’s just where you start.
Don’t get so locked into a five year plan that you miss opportunities that don’t fit the plan. Some of the best career moves I’ve seen people make were the ones they didn’t plan at all.
The Game Plan I Wish I’d Had on Day One
If I could go back in time and hand myself a sticky note, this is what it would say:
✅ Start documenting everything from day one, even if it feels pointless
✅ Ask questions early and often, Google first, then ask a human
✅ Get one solid entry level certification within your first year
✅ Practice explaining technical concepts to non-technical people
✅ When you break something (and you will), own it, fix it, learn from it
✅ Stop comparing your chapter one to someone else’s chapter twelve
✅ Find one person who knows more than you and buy them coffee repeatedly
You’re Going to Be Fine
That feeling on your first day, the one where your stomach is doing backflips and you’re convinced everyone can tell you don’t belong there? Every single person in that office had that feeling once. Some of them still do. The difference between you and the person who quits after six months isn’t talent. It’s stubbornness. You just have to keep showing up, keep learning, and keep being honest about what you don’t know.
Now close this tab, go drink some water, and write down one thing you learned today. You’re already doing better than I was.
Big Dog Cert
Alright, lemme give it to ya straight. No sugarcoating, no corporate fluff, just the real deal. I'm Mike. Fifty years on this planet, and I've done it all. I started out in IT back when "the cloud" was just what you saw out the window, worked my way through HR (yeah, I've been the guy who had to sit across the table from people and keep a straight face), and then did a stretch in sales where I learned real quick that if you can't sell yourself, nobody's buying what you're pitching. Three careers. One guy. Zero patience for textbooks that read like they were written by robots.
