What I've Learned from Philosophy Class
1) Question Everything--This goes back to the statement "If everyone jumped off a bridge, would you?" Just because one person makes a statement (i.e. Plato saying art possesses the soul) doesn't always mean it's solid fact. So just take a step back and think for yourself.
2) Observe as much as possible--This is a great idea that started with Aristotle and continued on through Philosophers such as Descartes and Hume. If you observe, then you can replicate the actions which have been previously observed, thus making your life a bit easier.
3) Know your "Self"--Descartes had a real problem with this one. It is important to be one with your mind and body to make important decisions on life. It is also helpful for inner peace.
4) Educate yourself--Think--how intelligent do you sound when you are calling everything a "thing" when you know what exactly that "thing" is.
5) Don't rely on fate for everything--Go out and be a "doer" don't wait for good things to happen--make them happen! Make your destiny what you want...don't leave it up in the air for the Gods to decide.
