You can't achieve greatness in anything by playing it safe. You'll never hit the game-winning shot if you’re gun-shy because of earlier misses. Failure is never fun, but it is part of success. If you can't bring a "next play" mentality to your work or your game, you can become your own worst enemy, holding yourself back from what you might become because you're afraid of what could happen if you try. Learn from your misses. Adjust when needed. But don't stop shooting.
