I've known this quote for many, many years. My high school p.e. teacher used to say it. He called it the five P's (each word of the phrase starts with 'p'). It held true then, and it holds true now. It's one of those phrases that is timeless. When you plan for greatness, the follow through comes more easily. For example, rather than try to plan for exercise on the day you want to fit it in, make appointments with yourself for the week and then don't cancel them. You wouldn't cancel a meeting, so don't cancel this meeting with yourself.
I'm a lover of life, an eternal optimist, and I have an intense desire to add value through simple living and positive vibes.
