Knowledge of Self is very important, you can't be living in a world pretending to be someone you're not. No one will ever believe in you, when you don't have the courage to believe in yourself. You can not live to impress others solely not giving thought to express your true being. No one wants to interact with a pretender, a fake, a wannabe.
If you have the words, there's always a chance that you'll find the way.
