Of course stroke is a difficult problem

Another great Seth Godin blog post. Ask your doctor why they are running away from solving 100% stroke recovery. 'It's hard' needs to maniacally laughed at.

Or, at the very least, the only problems that are left.
Difficult problems are rarely solved immediately, and sometimes they’re not solved the way we might have imagined, but with effort, they often yield.
