Everyone should carry these same traits whether you are elite or not. It doesn't matter what you are doing in life, you should still go after the things you want with intensity ( a never say die and I don't want to be second attitude), be focused about your goals (I want to lose 10lbs, not I want to lose weight), and be committed (even if you slip up and fall off the paleo wagon....get back on with the next meal).
So, no matter what your sport or what your goal is, live like you are an elite athlete. Challenge yourself, push your limits and notice the difference.
