Confidence is not waiting on the sidelines, laced up and certain, before the whistle blows. Confidence shows up in the chaos of playing. Decision is the playmaker; action is the shot.
Neither perfect preparation, nor a flawless game plan guarantees you won't miss or that you'll win. The only way to know is to do: Get off the bench and onto the pitch—legs unsteady, heart a steady drum, mind determined as they come.
Opportunities will slip by, the clock keeps running, possibilities will fade: That's the cost of the quiet hope of winning, of standing on life's podium and raising your trophy, whatever it may be.
Debating your readiness? Start already. Failure to do is certain denial of done—That feeling of "finally" comes only after you've begun.
