Passion, just keep walking and you will strengthen your back. You know if you don't use it, you lose it. The more you sit and don't work those muscles, the worse it is. I know pain makes you hold still. But, sometimes that is the worst thing.

And isolation is the same. If you hide, you lose your courage to go out. Bravery isn't the absense of fear, it's facing your fear. That's one thing I always try to remember.
