What doesn’t kill you makes you stronger.

This proverb is originate from,famous german philosopher ,Nietzsche's production.The meaning of this proverb is hard and tough experience makes you more stronger.What I like about this proverb is  giving me a power which makes me withstand the painful position.
I'v once fallen into so hard situation that I could't think positive way but now I sometimes remember in those days in order to ascertain how much am I developed.It is certain that we will face many difficult problems in the future but we could be stronger after overcome these problems.
