Life is pretty good.

People who complain about life are annoying. I have 4 AP classes, I finish most of my homework on time and I get at least 7 hours of sleep everyday. Life isn't that hard.

As a matter of fact, life is pretty easy. If you want a good grade, work for it. If you don't want to do homework, then don't do it. Just do whatever makes you happy, because let's be honest here being happy is the whole point of anything.  If doing something doesn't make you happy now or later on, then it's pointless. Don't waste time trying to do things you don't want to.

Another thing to consider is to not freak out about stuff. Seriously. First off it's bad for you, second off it's incredibly annoying to everyone around you. Especially me. Just go with the flow. Don't stress out about things, just fix them if you can. If you can't, oh well.

You kids stress out too much. Just take a step back and chill out, bro. Some things are out of your control and you can't change that.
Also, if homework is making you stay up to three in the morning then first of all your working habits are terrible, secondly you'd be better off not doing your homework. Work smart, not hard. If you can't work smart then don't work at all. It's more beneficial to get your sleep and be ready for the next day than to do some flimsy homework assignment that won't help you in the slightest.
