It's always too early to quit.

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

If you think you can do it, you can.

Things do not happen. Things are made to happen.

Problems are not stop signs, they are guidelines.

The dog that trots about finds a bone.

Quality is not an act, it is a habit.

To know oneself, one should assert oneself.

Expect problems and eat them for breakfast.
