Whenever you're called on to make up your mind, and you're hampered by not having any,
the best way to solve the dilemma, you'll find, is simply by spinning a penny.
No - not so that chance shall decide the affair, while you're passively standing there moping; but the moment the penny is up in the air, you suddenly know what you're hoping.
- Piet Hein
And if it doesn't help, if you still don't truly know what option you prefer, that means that the downsides and upsides of either are balanced so well you may as well pick whatever the coin landed on - the time you're wasting agonizing over the decision is worth more than the marginal improvement of picking the better option.
As with all advice, some people are on the other end of the spectrum and need the exact opposite advice.
You may be indecisive because you truly don't know enough about the options and need to do your research to make an informed decision. Don't overdo it, just do enough. How much is enough is not easy to say in general.
So I started using a shortcut. Instead of following the arguments, I observe the arguments themselves. Am I trying to justify a yes or a no?
Saves a lot of time. Just do what in your gut you’ve already decided to do anyway.
