Never complain and never explain.

The dog that trots about finds a bone.

Without hard work, nothing grows but weeds.

If you think you can do it, you can.

If you're going through hell, keep going.

The secret of getting ahead is getting started.

Quality is not an act, it is a habit.

Begin to be now what you will be hereafter.

To know oneself, one should assert oneself.
