"I have no idea what I want to do."
That means you don't want to do anything.
Because if you wanted to do it, you'd know.
(But I don't mean you won't find anything. You might find it soon, and you might actually just "want to do it", you might not have passion for it, but you'll be satisfied. And that's fine, as long as you think it's fine.)
(This was really scattered.)
(I might write a more detailed, eloquent post about it later.)
