somewhat serious response time...?
being out of school for about 5 years now, ill be completely honest with ya.
when i was in highschool i didnt do most of my work cuz the classes were relatively easy and lets face it, 15 minutes of mental 'sit down and fucking do it' should be more than enough. i was even at a all boys catholic school which was apparently way harder than the local public schools.
college though, you have the great opportunity to take classes you enjoy like someone said above, but in a liberal arts program you're certainly going to end up with some bullshit too.
i was your typical pot-head back in the day but i had at least a few ounces (pun intended?) of self respect and self control to the point where i just tricked myself into a reward-based situation. mind you i was also your typical ADHD kid and still take adderall cuz it helps at work, but i would just get myself pysched up, (not always but try to) and be like "listen fucktard (to myself) just bang out this bullshit and roll yourself a nice J and do whatever makes you forget that you were just doing homework". cuz honestly, especially in college, you feel like a total douchebag if u start dropping letters cuz of something as menial as homework. and for the most part, things like tests become easier.
i drank ALOT in school and still made time to get shit done, also had a roommate who was always out with me, but refused the basics (homework/going to class sometimes) and failed out 2 months before graduation because of it. was a total bummer.
real world rant though - depending on what you are studying, know that for the most part, the system is broken. i work in advertising, and other than basic reasoning, math (im a programmer) and critical thinking, none of the shit i learned along the way helped compared to real world experience.
great article for anyone interested in a programmers take on math and the overall concept of american schooling's ass backward approach:
