"The best advice I ever got was from an elephant trainer in the jungle outside Bangalore. I was doing a hike through the jungle as a tourist. I saw these large elephants tethered to a small stake.
I asked him "How can you keep such a large elephant tied to such a small stake?"
He said "When the elephants are small, they try to pull out the stake and they fail. When they grow large, they never try to pull out the stake again."
Moral - we have to go for what we think we’re fully capable of, not limit ourselves by what we’ve been in the past.
