Why......

Today while coming to office i was thinking of why am i doing this ....why am i getting carried away with what others are doing. I have done enough of study ...placed at a good paid job....then also sometimes i feel lonely even when i am surrounded by 100 persons. Why .... I am still planning to study more ....what will i get out of it. An additional degree...which will help in my career..may be yes or may be not...why there is no end to this ...when i was not married...i thought of getting married and settled in life ..then after marriage ..i thought of having kids and get settled in life ..and now after having my son in my life ..i am thinking of making his life good and do some investment for him and then get settled ..why i am not getting settled ....every time i am getting new destination ....is it the natural thing which is happing to me......but at the end of the day ..its a nice feeling when i see my son's smile ...i do everthing to make him smile...do every non sense activity ...make different type of faces....but when i feel alone ....i start thinking why i am doing this.....why..
