Hello! There are dozens of us
From my personal anecdote: I still think most people should at least try a class or two at uni before they make a decision. I left after a year, and I did benefit in terms of networking, building contacts, and free electrical equipment.
For anyone else reading this, and is considering jumping ship. I recommend:
1. Be honest with yourself: Why are you doing this? Is it because you don't like that specific university, or do you simply learn better on your own (whether it be online courses, MOOC's, or hands-on building)?
2. Have a plan b and c and d in case that job/apprenticeship/internship you left uni for falls flat. I was fortunate enough to have contacts back at the uni I went to, and got a research position after my consulting business dried up.
3. Have enough savings to last you six months at least, in case things go south.
4. Build a personal portfolio website! When submitting your resume, have the link at the top.
5. If you do pursue another endeavor, it's going to take time (years) to ramp up to the income level you desire. Not everyone is going to be Steve Jobs or Bill gates, however paying the bills and being your own boss isn't too bad, either.
The reason I am writing this is that when I graduated high school, I felt college was shoved down my throat and I "drank the Kool-aid" so to speak. People learn differently, and at different rates. This doesn't even account for the rising cost of tuition (at least here in the US). I wish I had a little more guidance then.
Figure out what works for You.
Cheers.
