Failure need not be final. In fact, it can also lead to great successes and advances. So many are afraid of trying new idea, new activities. 'I'd be no good at that at all,' we say. Or, 'There's no way that's going to work; - that just not possible.' Often then we stand there, watching someone else do 'the impossible' - doing it first, when it was our idea.
Someone has said, 'Writers finish their books not because they are disciplined, but because they believe in themselves.' Believe in yourself, trust God, believe that the vision, the good idea, that life-changing action can - and will make a difference.
Try. You'll likely fail. Try again until you succeed.
Above all else, get in the game!
