Secondary Chess skills?

So, I recently decided to take my chess studies seriously.  I have already rummaged thru the forums here and gathered the most highly regarded books to start my journey.

What I'd like to know is this:  What secondary skills/attributes would best support my understanding of chess?

So far, I have identified three areas: general learning process(how to learn), logic, and creative thinking.

Are there other areas you wise folk might suggest?

tactics

Military tactics(Art of War) type?

I dont think one should understimate physical fitness. It makes sense. Better stamina; more oxygen for the brain. And I think I remember that Fisher did a lot of workout in his early days, Carlsen sure does.

(hmm, come to think about it maybe that is why I am so lousy at chess...)

I'm no expert, but as a strong beginner, I've already noticed these skills have certainly come into factor: analysis, visualization, calculation and planning.

umm, not exactly; look up the tactics trainer on this website; it's a decent introduction

never mind; didn't realize by secondary your meant "non-chess"; actually Sun-Tzu is not a bad idea-  some of his tactics would actually apply quite well

Thick skin and big balls.

Yes, physical fitness. People always use the argument that the Olympics were supposed to be about bettering one's mind and body in order to get chess into the games, but the reverse should be true as well. People working to better their mental endeavors should not neglect their physical well-being.

i think meditation would be the best thing because it trains you to focus your mind on
