One key trait in becoming a successful lead is self-awareness.
To become self-aware, you need people who are willing to speak into your life. You need someone who will tell you the truth.

You have to begin by being aware that you want to be more self-aware. But you also need someone else you trust who is willing to speak truth to you.
