Failure is your key to success 

Failure is your key to success
Yes, it sounds perverse but it's true. Your greatest gains as a human came as a baby, you learnt to crawl, walk, talk, ride a bike. What have you achieved since?
You achieved so much as a baby because you were not afraid to fail. We grow up in a society where you are not allowed to fail. You are not allowed to drive fast, ride fast, risk your body, risk your money. You are conditioned to avoid failure at all costs.
Success however is determined by your willingness to fail.
Once you understand that and work out the worst case. You must take risks, You must be prepared to fail and success will be your reward.
Good luck.
