Choosing between good options

I listened to the podcast episode “What You Do vs Who You Are” and I get that those two things are separate. I love the idea that “who you are” is determined by your thoughts. That gives me a lot of confidence and comfort. My question is about the “what you do” part. If you’re someone who has a lot of interests and are still trying to figure out which path to pursue for work, how would you go about figuring out which one to pursue? I find all options equally interesting, but I think the best chance of success is for me to pick one and to take massive action. I know I’m indulging in confusion and should just pick one, but I can’t make a choice when they all seem like good choices. Thanks for the help!
