It doesn’t have to be the number of choices creating anxiety. Maybe an existing anxiety is pushing you towards seeing more choices to block yourself from committing on one, because you are too internally conflicted. Motivation has an internal hierarchy, you do a thing in the name of a more core thing in the name of a more core thing. But this is not a tree, you also have different parts of you wanting different, conflicting things at the same time. So a lack of decisiveness on the outside might reflect an internal conflict inside. If you side with one side of the conflict (starting with your semi pivot), the other side of the conflict might get stronger and more polarized. Same goes for medication, it will ease your decision making at the expense of silencing certain parts of yourself. There are good suggestions about externalizing this conflict to journals, talking to a therapist etc. I would also suggest doing less things (not siding with any of the conflicting parts for a while) and to actually listen to yourself. What is this all about? What is the core motivating factor all these parts are organized around? In the grand scheme of your life, is a startup is nothing. What do you truly value and find meaningful? Don’t be eager to come up with an answer but instead listen to yourself for insight. That might be what your anxiety is telling you anyway; “stop doing things and listen to me”.
