Do not get so concerned with making a living that you forget to make a life.
A mistake is valuable if you do four things with it: recognize it, admit it, learn from it, forget it
Discipline yourself, and others won't need to.
Do your best every day. Live each day as if it's your masterpiece.
Discipline of others isn't punishment. You discipline to help, to improve, to correct, to prevent, not to punish, humiliate, or retaliate.
The uphill climb is slow,but the downhill road is fast.
