If I had to guess, I would guess that people who fail are more likely to go on to be successful if they continue. They might learn from their mistakes, but mostly I think touching the bottom or losing everything lets you know exactly how bad the worst really is. And if it isn’t that bad, or isn’t as bad as you feared, then you feel very safe doing it again.
Imagine someone who is in water up to their chin as they tiptoe along the bottom of a pool. Now imagine someone who is treading water just a few inches above the bottom of the pool and doesn’t know where the bottom is and is afraid of not being near the safety of the pool’s edges or bottom. Which person has the advantage? Which person is in a better situation?
When was the last time that you touched the bottom?
