I think one big thing wouod be the human psychie (not sure if thats how it's spelt.)

So for example, I have recently been taking on a bunch of new hobbies and am just loving learning new things. This includes having taken on learning python. I spent the other day doing essentially what I would imagine could easily be considered tutorials for a starter course on python. As a student at varsity, I always had this feeling of disdain for work I "HAD" to do, and so I would drag me feet and do the bare minimum. Now that I don't need to do it, I'm spending hours doing just that and loving it. Where was the joy in the work at varsity. Why is it that because I needed to do it, did hate it so much? I would have done so much better had I been this excited about my work at varsity.

It's also not that I was doing the wrong work because I have had a similar reaction to work in the field I studied. Also I found my friends all had a similar reaction to tutorials and homework. We are strange beings.

That's just an example I have looked at how our mind works and gone, that is just so bazaar and illogical.
