Get out of your way and don't let others get in your way. Accept your failures and take the risks. Learn from them. Adapt. And give it another go.
Soichiro Honda (yes, the founder of Honda Motor Co.) said,
"Success is 99% failure."
Joss Stone put it this way...
"I've got a right to be wrong
My mistakes will make me strong
I'm stepping out into the great unknown
I'm feeling wings though I've never flown.
I got a mind of my own
I'm flesh and blood to the bone
See I'm not made of stone
Got a right to be wrong
So just leave me alone."
—Joss Stone, "Right to Be Wrong"
