"Investing is about making profits, not proving how right or smart you are. Don't internalize investment strategies."

Actually, many things are like this. Don't deeply bind your personal identity to certain behaviors. There aren’t so many things that need to be internalized to represent you.

Take yourself as the ultimate purpose of your journey on Earth, not measured by temporary gains or losses, nor bound by constant self-scrutiny and judgment. Everything should serve human free will and self-fulfillment.
