If you can dream it, you can do it.

If you think you can do it, you can.

The wise does at once what the fool does at last.

The most effective way to do it, is to do it.

Things do not happen. Things are made to happen.

It's always too early to quit.

Expect problems and eat them for breakfast.

The dog that trots about finds a bone.

Know or listen to those who know.
