Becoming the best is about never being satisfied with what you’ve done. It’s about continually improving who you are.
That’s why my final tip is the most important (at least, for me): See yourself as a student. When you teach, share your ideas, give advice, or lead people: Do it with the humility of a student.
But at the same time, I’m glad to see that people find my articles useful and that it helps them. You have to stay objective. If you’re good at something, acknowledge your strengths. That’s not ego.
