There are a ton of great ideas on "How To" do whatever needs to be done here on BP, but are there things each of us can do that don't require advice? Is there a natural force that will help you become happier with your life?

I've noticed that my day to day routine is ALWAYS positively effected by a good physical workout. When I get up in the morning and workout, be it an hour lifting weights, a brisk jog, some form of cardio, yoga, swimming...whatever, I've found a direct correlation to my actual ability to create success in my life. I'm more focused on what I do, more motivated to do it, more patient with clients & prospects, all my relationships both personal & professional improve, I sleep better, wake up easier, eat healthier.
30-60 mins/day of physical exercise make a BIG difference for me one way or the other. Not to mention I feel stronger & more confident.

Is it true for you? Have you tried? How important is physiology on your mental approach to business?
