Be grateful for what you have and stop complaining - it bores everybody else, does you no good and doesn't solve any problems!
You plus God equals enough.
A pleasing personality helps you win friends and influence people. Add character to that formula, and keep those friends and maintain that influence.
If it's a principle, it's a winner. If it's a tactic, it's a loser.
You measure success by how much good you do for others.
Nobody on the face of the earth can make you feel inferior without your permission.
