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.
The problem with today’s world is that everyone believes they have the right to express their opinion AND have others listen to it.
The correct statement of individual rights is that everyone has the right to an opinion, but crucially, that opinion can be roundly ignored and even made fun of, particularly if it is demonstrably nonsense!
As you travel along the roads in life, there is a certain kind of peace that comes with knowing you're on the right path. And when you are faced with adversity, it challenges you but makes you stronger. The road is not always an easy route. Nevertheless, you must not allow your fears to keep you from reaching the destination.
When you speak, be sure of what you are speaking. Don't be rambling full of words that have no integrity or truth. Nobody wants to confide in you when they doubt what you say. If you are filled with untruths, those characteristics make it hard for anyone to believe in you.
