No risk no reward, that's just the logic.
However, no one enjoys failure, and no one wishes to experience it, but the truth is that, if you're not failing, apparently you're not risking much, and when you don't risk much, you won't gain much.
Life rewards the risk-takers who are to take the risk to fail and all that comes with it, but some people run away from risk and tend to settle for what's easy ... This differentiates the doer's from the wait-n- see'ers. In the journey, if becoming rich, one must set aside fear of failing.
