Unsure If You'll Regret It, Do It

Whether in life or in an improv scene, we are often faced with two options, to do or not to do. Research says you should you do:

Using a random-digit telephone survey, respondents reported a salient regret, then answered questions about that regret. Results showed inaction regrets lasted longer than action regrets, and that greater loss severity corresponded to more inaction regrets.

So use your judgement, if you're not sure, go for it. If you're wrong, then it will just be a sunk cost.
