A big part of my satisfaction in life is, and has long been, feeding what makes me tick. I love a challenge, adventure, continuous learning, new experiences and self-sufficiency. What I don't like is having a lot of structure imposed on my day, spending time with people "because it's what I have to do", seeking status, and suffering repetition and predictability over the long term. 

So what? I think it matters because knowing these things about myself helps me understand what I am naturally good at and what I should avoid. And, if I seek out and work on what I am naturally good at, I will likely produce better results for myself and others.
