My first experience with Uni was horrible. I was hoping to learn serious computer science, but got disappointed by maths, physics, electronics, etc. I was one of the best at programming, but overall result was very poor, I was one of the worst. Additionally I failed calculus at 1st semester (but other exams were passed) what made me depressed and I did 1.5yr pause doing completely nothing (barely used computer-I started hating it).
Now I'm 22. Decided to start one more time at the same Uni, same faculty, second semester ahead. I'm getting average (or little below avg) marks. I became more focused on non-IT-classes, because I managed to find ways how can those math/phys "things" can be used in practice.
Result:
+I became little more self-confident, headstrong, hard-working guy
+I developed ways to be more connected with people
+Forcing myself to study things I don't like (physics) somehow makes my brain smarter, nimble, flexible
+I don't struggle with procrastination
-Being older than the others in group is little bit uncomfortable
-Problem with employers asking questions about that pause/harddepression period
-Endless comparisons to younger friends in my mind
