Instead of finding reasons why you can't, find reasons why you can.

It always seems impossible until it's done.

Everything that happens was once a dream.

Hope might be a good breakfast, but it makes a very poor dinner

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

Don’t hang your targets after you’re done shooting.

The power of reflection is the most powerful skill you’ll learn.
