Antonie Walker scored more than 15,000 points across 13 seasons in the NBA.

"Believe me, man is capable of somehow creating more Bitcoin... They tell you there are rules and they can't do it. Don't believe them. When there is enough incentive, bad things will happen." -also Charlie Munger
The Solution: Humility
Humility is our learning muscle. It gives us permission to publicly admit failure. We're then free to explore why and hopefully update our perspective.
Reacting defensively to accurate feedback or evidence creates a barrier for growth.
As we can learn from Warren Buffett, avoiding problems is easier than solving them.
