Recenberg 1/5th success rule applied to life..

For those who are not familiar, Rechenberg's 1/5 rule refers to adaptive mutation in evolutionary strategies (ES). It says that the ratio of successful mutations to all mutation should be 1/5. Deriving from this idea, if you get too successful (i.e., more than 1 out of 5 tries) then you're converging too fast to a local optima (aka safe options) and will result in stagnation later on. So, don't run after too many successes. Ideally, at-least according to Rechenberg, one should try 1 safe thing for every 4 risky things in life to optimally balance stagnation vs. growth.
