Discipline in your life outside of poker +ev?

I was reading a blog about a guy who was a blackbelt in a martial art and how that kinda shaped his mindset for how he approached poker.
I realize that I don't do much outside of poker as far as a hobby that requires loads of work and discipline so I was wondering if some sort of physically/mentally challenging activity has translated into success on the tables for anyone here.

I was thinking like tai chi or something lower impact than Taekwon-do, maybe even yoga. Something that gets me active and also requires my mind to focus etc.
Other than work and go for the occasional walk I don't get much of that in my day to day life. Maybe I could even get some religion. (please don't any atheists go nuts on me) You know what I mean though. Work parts of my body and mind I don't right now.

Spiritually or otherwise. I know businessmen read Sun Tzu in order to gain perspective or a new approach to the business world. Anyone do that in poker?

Here is the blog I was talking about. http://www.giantbuddhapoker.com/giantbuddhas-blog/

having something outside of poker to keep yourself in shape is a must do. whether it be going to the gym or yoga you need to get out and keep in shape. working out also helps your mental health which is obviously a big part of poker.

Well Paul actually visits this forum quite regularly. If you search he actually has a thread where you can ask him these exact questions. Just search for Giantbuddha. Definately worth while, if i decided to take up playing limit holdem, i would definately buy that book. You know what, i'm probably going to get it anyway!

Apart from that, a book that is definately worth checking out is "think and grow rich". It's a really old book, but millions we're spent in the development of it. It's basically a 'formula for success'. They interviewed something like 50 of the most succesful people in the world at that time. It's uncovers what the linking quality is in those people. Definately a must read in my opinion. As i believe having something that motivates and drives you, is going to give you that energy and focus your talking about.

WiZZiM thank you! Imagine my luck lol.

I'm starting Tai Chi next week since I found a place that teaches it near me.

I'm a black belt in Jeet Kune Do , Tang Soo Do , and Hapkido.

It does help with the poker skills
