I tend to think that physical, mental and spiritual strength are some of the most important aspects of survival, or really any difficult challenge we are apt to face in life.

I've been looking for something to keep myself motivated with my physical fitness and stumbled upon the Spartan Race. They have an e-book available that I've started reading and it made me realize that while we often stress the physical aspects of training, we have a tenancy to overlook mental aspects (or at least I did).

While I wasn't too surprised when I read a section about the importance for mental toughness, or grit, I found it very interesting that their training template to prepare for a race included mental exercises (e.g., mental math, memorization, etc); not just the physical training I would have expected.

I'm now convicted and am going to try and ensure I am exercising mentally, not just physically, as a part of my regular routine.
