we do some mistake in our life that burns us full life time.at first i was selected for admission in a university that is first ranked in my country.but i had a mistake, as a result i couldnt admit there.now i am persuing my bsc degree in a university that is third ranked in my country in applied math.but i am little happy now.that mistake makes me crying.so we all must be careful in every step.

thank you for this post.... @kaylinart
