Thank's for your suggestion
that help me to manage my money
before i know Bitcoin my salary only from office (real work/not online) after i know i can earn some amount from bitcointalk (signature campaign)
i get 0,035
BTC/week or 0,14
BTC permonth
im not think about cash reserves- medical insurance, retirement, life insurance etc. after i reading i will save my money from bitcointalk to do it
I think 0.07/month is enough to it
Thanks to me.

and also thank you for believing my way how to saved my money, because now a days teenager or employed people don't think or they not believing in saving. They just only want to spend their money in their own way, their not thinking about their future, when they not have a job, or incase of emergency etc.
teenager now does not think about his future, because they assume that they have rich parents, and they will get his money someday, indeed very unfortunate this, perhaps the role of parents should be considered in this regard
