“I still find that, in general, having a plan is, well, a good plan. But when my carefully laid plan laughed at me, rather than clutch at it too tightly I just made a new one, even if it was one that didn’t immediately make sense. In blindly trying a different path, I accidentally found one that worked better. So don’t let your plan have the last laugh, but laugh last when your plan laughs, and when your plan has the last laugh, laugh back, laughing!”
