If you don't know how to succeed at life, you should at least know how to fail... so you can avoid doing that thing of course.
In that vein, I came across this tweet with a quote from Tim Ferris' book Tribe of Mentors that I thought was really worth sharing.
This is about as true as it can get. One of things you have to learn how to do in life is to let people down. It's literally impossible to please everyone at the same time. Even if you sit on the fence, some people will hate you for being a fence-sitter.
So if you don't know what to do, at least stop trying to please everyone all the time.
