It's always too early to quit.

Imagination is the true magic carpet.

When learning stops, decay sets in.

Stand up to an obstacle. Just stand up to it, that's all, and don't give way under it, and it will finally break. You will break it. Something has to break, and it won't be you, it will be the obstacle.

Christmas waves a magic wand over this world, and behold, everything is softer and more beautiful.

Believe that all the resources you need are in your mind. That is a formula that really works.

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