Believing in negative thoughts is the single greatest obstruction to success.
I find no importance in showing others that I am happy; it's not important to me that they know or think that I am happy but what is important to me is that I am happy. I am interested in being happy, not in making others think or know that I am.
You have two choices, to conquer your fear or to let your fear conquer you.
Instead of complaining about the problem and blaming others, start finding the solution.
Celebrate who you are in your deepest heart. Love yourself and the world will love you.
