Successful people do this. The wise sages of our time did as well.
Self-awareness is an asset, although not always so easy to achieve.
It's a constant work in progress. You have to step away from the scene in front of you and observe everything from the perspective of a witness.
The next time your emotions are heated, before you act, calm down, step back - and observe.
This helps to inspire intelligent action from a place of wisdom and maturity... instead of an emotional and heated reaction.
