From Seth Godin. For stroke I think the possibility is that all stroke survivors can get to 100% recovery. The reality is that your doctor and hospital do not believe that and don't even want to attempt getting there. Damned lazy fuckers.
We must avoid the temptation to begin with an analysis of what's easy, or what's probable, or even likely.
We can only do our work justice by examining what's possible, and then deciding if we care enough to pursue it.
