When you believe you can... you can!

Get yourself a goal worth working for. Better still, get yourself a project.

You may live in an imperfect world but the frontiers are not closed and the doors are not all shut.

Your automatic guidance system cannot guide you when you're stalled, “standing still”.

We simply must get it through our heads that holding a low opinion of ourselves is not a virtue, but a vice.

Happiness is native to the human mind and its physical machine. We think better, perform better, feel better, and are healthier when we are happy.

As soon as the error has been recognized and corrections made, it's equally important that the error be forgotten and the successful attempt remembered and dwelt upon.
