“If You Fail, Never Give Up Because F.A.I.L. Means “First Attempt In Learning”. End Is Not The End, If Fact E.N.D. Means “Effort Never Dies.” If You Get No As An Answer, Remember N.O. Means “Next Opportunity”, So Let’s Be Positive.”
When you know both yourself as well as your competition, you are never in danger. To know yourself and not others, gives you half a chance of winning. Knowing neither yourself or your competition puts you in a position to lose.
It's the action, not the fruit of the action, that's important. You have to do the right thing. It may not be in your power, may not be in your time, that there'll be any fruit. But that doesn't mean you stop doing the right thing. You may never know what results come from your action. But if you do nothing, there will be no result.
