You will never truly understand the struggles of another person. Remember to realize how hard your own struggles are for you. The other guy feels the same way. We are all trying to make our way in this world so make it easy on everyone and don't judge.
My most favorite quote of ALL TIME by Tupac, should read ".or you can just leave the pieces on the floor and move THE FUCK on." explicit but rolls off the tongue better once you finally get to that point.
