Some people lose. Some win. Rest live in mediocrity.
We are careful in whatever we do. We tread cautiously to ensure nothing goes wrong. Most of us succeed in not losing. And we live happily ever after in mediocrity.
Reducing caution increases your chances of losing. But you have no other option. You cannot win a football game by just defending your goal. You can, at best, stop the other side from scoring, and hence not lose. If you want to win, you need to play to win. You need to weaken your defence in order to improve your offence and score goals.
Reduce caution and take risks. Play to win instead of playing to not lose.
