Uncertainty.

Read and stay super mentally fit. Find, support and be loyal to great friends and colleagues. Remind yourself you live on a rock spinning through space populated with humans not an air-conditioned management model with perfect emotional intelligence robots. Celebrate certainty when you get it, sure. Strive for it, definitely: the quest is (literally) enlightening. But get comfortable, really comfortable with living with uncertainty. And then Life becomes so much easier, more relaxing and ..er.. certain.
