It starts inside your head, and your heart. You will never be able to shame yourself into doing better... that doesn't work. But what you can (and must) do is to love yourself. To think so highly of yourself that you KNOW, right down to your bones, that doing better is what you are meant to do. And will do.

After that, it simply becomes the physical manifestation of the Grinder's Philosophy. Do a little bit more, and do it a little bit better... each hour, each day. Each month. Year. Decade.
