On successful people(like Elon Musk):

Keep your body sharp to keep your mind sharp. It's pays off.

They will experience heroic, spectacular, humiliating, very public failure but find a way to reframe until it isn't failure at all.

When they fail in ways that other people won't, they learn things that other people don't and never will. They have incredible grit and resilience.

Surfing the net is a deadly timesuck; and given that they know what their time is worth--they can't afford it.
