Never complain and never explain.

By failing to prepare, you are preparing to fail.

Quality is not an act, it is a habit.

Wherever you are - be all there.

Begin to be now what you will be hereafter.

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

Go for it now. The future is promised to no one.

Be gentle to all and stern with yourself.

Always desire to learn something useful.
