Backbiting is the attempt of one who is incapable of doing better himself
Not to postpone is strength in action
Set your heart on doing good. Do it over and over again and you will be filled with joy
There is a voice that doesn't use words, Listen
Work is the thing upon which everything else in this world depends
To improve is to change, so to be perfect is to change often
