Why?

Why do we do 'what we do'? Why do we stuggle.. why do we do everthing that we do .. Is it because everyone is doing it? or is it THE RACE towards infinite space just to see who travels more before he or she dies.The only rule of life is to be alive!I think we can do anything we like as long as are happy, satisfied and do not interfear other's life.Its society what says you need to study had and be a great person in life.BUT i think we don't have to be engineer or a doctor.. or somthing great to be a great person. I think That only works within the limits of society.but if you happen to ask yourself what is your goal in your only life then its nothing more than satisfaction and happiness.
