Never complain and never explain.

To know oneself, one should assert oneself.

Quality is not an act, it is a habit.

By failing to prepare, you are preparing to fail.

The dog that trots about finds a bone.

Well done is better than well said.

If you think you can do it, you can.

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

Problems are not stop signs, they are guidelines.
