"Always bet on the optimist in the short term and always bet on the pessimist long term. The optimist will be right until he is wrong, and the pessimist will be wrong up until the point where he is right."

Systems tend to be quasi-linear for perturbations, i.e. a small change in inputs will result in a small proportional change in outputs.

However, real systems are non-linear for large perturbations, i.e. a moderate change in inputs results in outputs which are essentially unpredictable.
