Ford isn't simply cheerleading for positive thinking—he's describing a psychological trap that works both ways equally. Your belief doesn't magically alter reality, but it determines which obstacles you'll even *attempt* to overcome and which you'll surrender to before trying. A pianist convinced of her clumsiness won't practice the difficult passage that requires three weeks of work; a pianist convinced she can master it will endure those three weeks and likely succeed. The real power lies not in wish-thinking, but in how conviction shapes the effort you're willing to invest.
