stay or go?

confused in life and lost in thought
am learning things that can't be taught
always wanting never got
might as well forget the lot
I'm gonna lose i know the score
I've seen it many times before
why start climbing just to fall
why chose love to lose it all
shouldn't be bitter, shouldn't get mad
should remember all the good times had
make a decision make up my mind
stick this path out or leave it behind?
