Be yourself??

This may sound stupid, but what does it mean to be yourself? Like, how do you know what yourself is??

what you like.. what do you like?? do you like the colour pink or the colour blue?? don't like something because someone else does.. don't be like them.. be yourself ^_^ like the colour blue because you like it, not because they like it!!

it's just something stupid people say when they don't have good advise to offer

means act like you would if you were at home. Just do whatever comes naturally.

It's a difficult question. Because we're so influenced by everything, that at the end of the day yourself has very little meaning. But generally it means what makes you happy... The person who you are where you're not putting up and act, the person you truly feel most comfortable being (this is sometimes hard, we're so used to putting up fronts...)
