Nada

the truth is.sometimes you do good and good is done to you. sometime you do bad and misfortune comes to you. it is also true that sometimes good people face misfortune and bad people prosper.so it follows therefore that life is not or does not describe a linear function but rather a cubic one. life will screw you, people will let you down, but sometimes they will exceed your expectations. there is no telling. my philosophy has alway been that: LIFE DOES NOT OWE YOU SHIT! so dont nobody screw you up, do not expect anything from people. count only on yourself and expect only from yourself. if others come thro for you, let it be a pleasant surprise, not an expectation. that way you will be at peace with yourself, others and your God
