Because if you really were in control of who you are, you will understand that nobody's opinion of who you are can change how you view you.
Don't focus on trying to be 'the best'. Focus on being irreplaceable.
Don't stress over people in your past. There's a reason why they didn't make it to your future..
See, the ‘small stuff’ is what makes up the larger picture of our lives. Many people are like you, young man. But their perspective is distorted. They ignore ‘small stuff,’ claiming to have an eye on the bigger picture, never understanding that the bigger picture is composed of nothing more than-are you ready?- ‘small stuff’.
Do not change your shape and aura to fit other people's puzzles stay true to the fabric that makes you, you.
