You can't be afraid of failure and you can't be afraid of success, because either one gets in the way of your work.
Success and failure are both part of life. Both are not permanent.
FAILURE, SUCCESS AND FAILURE ARE BOTH PART OF LIFE
Develop success from failures. Discouragement and failure are two of the surest stepping stones to success.
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
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.
