Self-observation the way to sharpen abilities

"How do you get so good?" Pegs asked.

Self-observing my own behaviour and its consequences is a way I sharpen my self-management abilities.

This is a personal example: sometimes at meetings I feel that I'm talking too much. It's a typical sales malady. There are times to talk and times to listen, but at the start it's an effort to control my own behaviour. Now, by keeping conscious about it, I can tell whether I am saying too much.
