Failure is one of the surest stepping stones to success.
No element can do as much for you as failure can,
if you're willing to study it and make capital out of it.
View every problem you encounter as an opportunity.

There is always a good side to every situation.
Stay optimistic and try to see an opportunity in your problems,
not pessimistic and see problems in every opportunity.
The optimist sees the doughnut, the pessimist sees the hole.

When it is dark enough you can see the stars.
