Someone once asked...
Someone answered with kindness...
I think you are not alone in that question at all and it is something lots of people struggle with. But I think it is a question that is impossible to answer from an armchair. You can only go out into the world and try things and from that empirical experience you realize that you enjoy something, or maybe you meet someone or something happens that shapes your perspective on what's important to you. But you can't find that by analysis alone in a vacuum, it's only the real world that has texture.
