That's it; I challenge you to answer these three things either publicly or privately to your self.
What do you believe
Do you really like yourself
What do you think about yourself
You might find daily or even hourly that these answers and how you feel about these answers will change. You can read nearly any self help book and it will suggest that your mind will control your reality.
My task for you is to see in yourself how you are in this moment and how you can take that to move forward and grow; it really is that simple.
Change starts with the self so if you really want a better world make a difference in yourself; Good Luck.
