Justin, you’re encountering the classic conflict between the idealism of your youth and inexperience with the cynicism and reality-check of those of us who have been in the field a long time.
Colleges are very sheltering institutions, and often paint too rosy a picture of the opportunities that exist in the professional world. I know this because, as a person in my 40s, I only recently completed my undergraduate degree from a typical 4-year university (after well over 20 years of trying), and am now in a graduate program (I’ve also been in the IT business for close to 20 years). Many of my classmates were full-time students who started directly from high school and had little to no working knowledge of the workforce. I also tolerated the university’s frequent rah-rah speeches that were just naive in and of itself, but were targeted at those very same student demographics; people like me (working adults attending school part-time) were completely ignored because we were in the minority.
It gave my younger classmates a lot of false hope and inflated expectations.
Those signs are present in what you’ve written and how you’ve written it.
This isn’t meant to crush your dreams or tell you that you can’t do something. This is instead a warning to temper your expectations with a dose of reality from those of us who’ve walked this path before you. You don’t have to follow in our exact path, but you do need to understand that fundamentals and foundations exist for a reason.
You’re absolutely right in that you can achieve what you want if you put in the work and effort and patience. But what you’re asking for in your first post – a remote, part-time job in network administration when you have no practical experience – is not the function of time, work, effort, and patience.
It’s fantasy.
That’s what the others are trying to tell you.
It’s akin to a 16-year-old kid who just got his driver’s license, the only experience driving being the road test, and thinking to qualify as a taxi driver in 2 years. Or someone who just bought a guitar, learned a couple of chords, and presumes to be in a band touring arenas around the world with a year’s worth of lessons.
What you’re hoping to achieve is a pie in the sky. Can it be achieved? Possibly. But it’s not going to a person with no professional experience, no matter how much self-belief you have. That’s just reality. You may achieve that some day, after you’ve gone through the trenches, built up your professional resume, learned from mistakes, and gotten a solid handle on the actual profession itself.
A final analogy: the percentage of musicians and bands that hit the global stage, whether it’s Taylor Swift, Metallica, or Kanye, is incredibly minuscule compared to the percentage of artists who don’t make it.
The percentage of people who find and keep satisfying remote work in any discipline is but a drop in the ocean of the rest of us who are relegated to on-site, typical working conditions. Those who do had that magical combination of experience, drive, and, quite frankly, luck.
If there was a magic formula to part-time remote work that still paid the bills…don’t you think we’d all be doing that now already?
