Potentials?

I started reading a monograph by Jim Collins, called Good to Great and Social Sectors and one particular line reminded me to constantly progress, "no matter how much you have achieved, you will always be merely good relative to what you can become." I've always used the term, "potentials." Yes, it's not a word that is normally pluralized but, I've always felt that my potential today exceeds my potential, yesterday and my potential tomorrow exceeds my potential today. Anybody doing anything great today?
