I believe I can learn from my own mistakes and from the mistakes of people I admire. This connects with my broader emphasis on learning in continuous learning as an edge.
I remind myself that everyone is flawed, so when I learn from or imitate someone, I should try to adopt their good qualities and avoid their bad ones. This is a goal for how I learn from people, not a detailed test for distinguishing good qualities from bad ones.
Learn from your mistakes and the mistakes of others you admire.
Realize everyone is flawed, so try to copy only the good and none of the bad.
