Once you start a working on something, don't be afraid of failure and don't abandon it. People who work sincerely are the happiest.
Every adversity, every failure, every heartache carries with it the seed on an equal or greater benefit.
Even when you have doubts, take that step. Take chances. Mistakes are never a failure - they can be turned into wisdom.
FAILURE, MISTAKES ARE NEVER A FAILURE
The great question is not whether you have failed, but whether you are content with failure.
