Be strong enough, and you can bull through pain.  Be clever enough, and you can save your strength.  Be aware enough, and you can sink deep into the moment, appreciating every second as a self-contained miracle that configured itself through some amazing iteration of gravity/matter/energy.  Because sometimes, [strength/smarts/wisdom/cleverness/etc.] will not be enough.  The only choice you will have is to experience that moment as fully as possible.

 (You might even be able enjoy it )
