It doesn't matter how many times you have failed.... What matters is the successful attempt.

You can do only one thing at a time. I simply tackle one problem and concentrate all efforts on what I am doing at the moment.

People who say that life is not worthwhile are really saying that they themselves have no personal goals which are worthwhile. Prescription: Get yourself a goal worth working for. Better still, get yourself a project. Decide what you want out of a situation. Always have something ahead of you to “look forward to” — to work for and hope for.

When you believe you can... you can!

Forgiveness is a scalpel that removes emotional scars.

See yourself reacting to threats, not by running away or evading them, but by meeting them, dealing with them, grappling with them in an aggressive intelligent manner.
