In his letter to shareholders back in 2016, Jeff Bezos gave the best advice I’ve ever heard on how to stop procrastinating:

“Most decisions should probably be made with somewhere around 70% of the information you wish you had. If you wait for 90%, in most cases, you’re probably being slow. Plus, either way, you need to be good at quickly recognizing and correcting bad decisions. If you’re good at course correcting, being wrong may be less costly than you think, whereas being slow is going to be expensive for sure.”

What Bezos is saying is that you should think like a C student. When you’re about 70% sure, you take a guess and see what happens.
