We are sold certainty from the earliest age. The reason for anything and everything is to increase certainty. Qualifications will increase the certainty of a 'good job'. A daily multi-vit will increase the certainty of good health. A logo in colour red increase the certainty of success, a nice smile the certainty of winning the girl, a ...and so it goes on. But the wiser we get, we realise that certainty is just an occasional fortunate blip in a vast ocean of uncertainty. Uncertainty of weather patterns, of how customers will react, of the economy, of how our kids will respond to endless exams...And that long conditioning of expecting certainty causes us to feel unsettled, disappointed even. Craving a 'tick in the box', a reliable metric, a definite wedding day without rain.
Forget it. 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, definitley: 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.
