About-to-be HS Sophmore here, and I'm not sure what I want to do in life.
Right now, my main interest is in netsec/infosec, has been for the past 2 years. Yeah, I'm interested and all that, but there's definitely doubt lurking about it. I like it, sure, but I'm not really sure if it's something I'll want to keep doing after 20+ years doing it. I've never really felt passionate about something in the way I think that I could spend my whole life doing it (although what I'm interested in now is the closest it's come to). Along with the seemingly constant questioning starting from 7th grade to choose what you want to do as a career, it feels like there'll never be enough time to decide what you really want.
