FAILURE
Develop success from failures. Discouragement and failure are two of the surest stepping stones to success.
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.
Failure doesn't kill you... it increases your desire to make something happen.
FAILURE, IT INCREASES YOUR DESIRE TO MAKE SOMETHING
If you're not failing every now and again, it's a sign you're not doing anything very innovative.
