My body is f*cked.
What's the best way to proceed? Well, that's a tad complicated to answer - we're all snowflakes (translation: no, it's not that you're soft, but you are uniquely injured).
There aren't many worse feelings than knowing you are forever physically limited. And if you fit into that category: I am sorry. But here's the key: you cannot, and should not, feel sorry for yourself. It beats the alternative (you know, not having a living, breathing body with flowing, pumping blood).
In this vein (pun intended), our goal is to use what we have. It's to work with the hand we have been dealt. It is to not stop at the first sign of danger - it is to see the danger, acknowledge it, and then move the fuck on.
You are not on this earth to sit still. You are not on this earth to waste away. You are not on this earth to do anything other than to inch closer to your potential.
And so yes, there have been moments where the circumstances around you amounted to something significant. In this game of "health roulette," we lost. But so be it. Do what you were going to do anyway; why let anything stop you?
