Who decides whether you shall be happy or unhappy? You do!

Our problem is to become acquainted with our own selves, letting our personalities loose upon the world for the sheer adventure of their full development and in the positive hope that they may in their own way lift the level of humanity.

Any fact facing us is not as important as our attitude toward it, for that determines our success or failure.

The mind quickly responds to teaching and discipline. You can make the mind give you back anything you want.

Practice hope. As hopefulness becomes a habit, you can achieve a permanently happy spirit.

If you want a quality, act as if you already have it. If you want to be courageous, act as if you were - and as you act and persevere in acting, so you tend to become.

When you wholeheartedly adopt a 'with all your heart' attitude and go all out with the positive principle, you can do incredible things.
