If someone does not believe in doing their very best, they will do just what it takes to get by. Quality work adds value. Defective work causes rework and sometimes actually destroys a project. He will serve before kings. He will not serve before obscure men.

It is the way we should live our lives. Of course, we'll never be perfect, but that doesn't mean we should not strive for excellence. The best way to succeed in your work is to build your skills. This takes time and effort, but it is well worth it. I remember hearing someone say one time that if you spend just thirty minutes a day studying your own chosen profession, your income will double at least.
