When you're faced with a decision, but your brain is a sieve of indecision, fear not of the outcome, but of the unknown outcome, fear of not knowing the outcome.
Close your eyes, pretend you're in a meeting, and just start talking.
Flip a coin, but only if it's a shiny coin.
Ask a friend for their opinion, and then do the opposite.
Just stare at the floor for a few hours until the problem goes away.
