Question mark, The life.

Thinking about future,planning for future such as studying,working,marriage,kids,.... make me nervouse and anxious .
I do not really know what happens in future but life proves it to me that I myself and the role of I myself is the most important and major one in the path of the life.
When I see couples who have been living for about 15 16 years and they have just involved with their kids I feel that their life is just become a one dimention life.
The rules of the families and their impact on our life, reformation and somtimes breaking the rules by new ages.
Doubt, Doubt and doubt.
Dilema,Dilema and dilema.
