"If you want to achieve excellence, you can get there today. As of this second, quit doing less-than-excellent work."
Thomas J Watson
I think what this guy means is that everyone has the potential to be excellent, but in order to be excellent, you have to try to be excellent. For example, if you are writing a book, and you want it to be the best, you have to have that goal in mind so you can work for it and in the end you goal will become reality and you will  be proud of yourself but you have to want to do it.
