The upside of failure is that it yields greater opportunity for reflection than success.
There is, of course, the off chance that your failure hurts so much that you can’t bear to look at it or that it stops you dead in your tracks (perhaps literally, why hello, mama grizzly!). Think of it colloquially: people ask, “What happened??” after a failure, not a success. We’re generally better at learning from failure than from success. Lives comprised of strings of successes are usually the boring kind and the successes are generally mediocre (no empirical evidence to back that up).
The most successful people I saw while managing the business were always on and always had to be doing something. Many of them simply tried different tactics when one failed, a strategy that is not without its merits, but it seemed that they rarely gave much thought to what they were doing and what their goals meant. Maybe this is just a reflection of my own bias. But it seems that those who keep finding little successes don’t reflect or tinker with their strategies. This is fine in a zero-sum, binary outcome game, but life and businesses successes are not binary.
