Anything you do to and for another person, you do it to and for yourself
By all means tell the world how good you are - but do it with actions, not words.
You have within you all the power you need with which to get whatever you want or need in this world.
You can do it if you believe you can.
When your desires are strong enough you will appear to possess superhuman powers to achieve.
A man is as big as the measure of his thinking.
