My first day

My first day in life , something I always thought about. I know when I was born but did I add any thing to this world? I always dreamed that I will add something to mankind but the only thing I did manage to add is two kids.
Life is a strange series of events starts with the day you were born and since this day you have no control over it.
How really you can control your life? If anyone manage to answer this question please let me know.
It is kind of depressing when you think about it that way but it is the way it is.

P.S I don't even know why I am writing this in the night from the middle of the Sahara desert. How I ended up in this place?
