"Because it's there..." and "because it's addictive."

Ben Saunder's lovely TED talk about getting out and living life. I can't claim I found this on my own; the lovely Crossfit616 in Grand Rapids has a blog (which I follow) and they mentioned it (and cited where they found it).

Ben is right -- it can be addictive. But the mindset has to be there to want to push the envelope and not settle. So, push, people. Push. 

Side note: if you're in Grand Rapids, Michigan and are XFit inclined, check out Crossfit 616. Seriously awesome people who are amazingly welcoming and cheerful about wanting to get in a good hard workout. I did "Murph" for the first time with them over Thanksgiving break. About killed me. I loved it.
