Ability is what you're capable of doing. Motivation determines what you do. Attitude determines how well you do it.
Motivation is simple. You eliminate those who are not motivated.
It's not the load that breaks you down, it's the way you carry it.
When all is said and done, more is said than done.
You'll never get ahead of anyone as long as you try to get even with him.
Your talent determines what you can do. Your motivation determines how much you are willing to do. Your attitude determines how well you do it.
