One thing I read on HN a couple of month back and really clicked with me is:

"If you really struggle to decide between two options and you begin to waste time by postponing the decision, this often indicates, that both options are very similar in expectable outcome"

At least in situations, where you can't access more info about path A or B, indecisiveness may indicate "go flip a coin"

Sounds simple, but made me aware and helped in a few situations not wasting time already.
