One of my favorite ways to make crucial decisions is to use Jeff Bezos' famous 70% rule. Make decisions with 70% of the information you wish you had. Yes, everything is not figured out but if you don't do it, will someone else? Weigh the need for accuracy over good enough data for speedy decisions. In some cases, if you wait for more information, you could be late and lose. Of course, you will need to adapt and change eventually but get moving.
