When you spend a lot of energy trying to prove yourself to others, trying to prove to others your best, you don't even have the time to prove yourself.
You need to focus on proving yourself whether people see you or not. The main focus in life is to keep improving yourself. You have a high dream you have to achieve and you have to keep achieving it and stop worrying about what others think you are or the position they feel you should be.
You have to keep improving yourself and with all your energy, keep improving yourself so that you don't have any time to prove yourself again. That is how life is.
Don't waste your energy proving yourself again.
You can improve yourself and be the best in everything you do. That is how life is and that is what you can never escape in life.
