Believe in yourself! Have faith in your abilities! Without a humble but reasonable confidence in your own powers you cannot be successful or happy
Learn from the past, set vivid, detailed goals for the future, and live in the only moment of time over which you have any control: now
Humble yourself before the Lord; He will lift you up
He that humbles himself, God will exalt; he that exalts himself, God will bring to abase. He'll bring him down. Always keep humble, and be little in your own sight. No matter what God does for you, just see how much more humbler you can be all the time. More God blesses you, just keep getting more humble all the time. He can continue to bless.
But when you get to a place that you think, "I got it": you haven't got it; you're on your road out (That's right. See?); you lose your influence; you lose the--your strength of your testimony.
