Making Decisions Happy either way

I’ve posted about making tough decisions in here and the coach will ask, what would you decide if both results could be perfect? If we can be happy either way (find perfection) with our results, how do we know which one to choose? If I choose to be happy right now in this moment, every moment, with whatever happens, how do I make decisions when they arise? I do I know if left or right is the way to go when either or will result in perfection?
