ADHD and Ambition

I'm at that point in my life where I am graduating from young adult to adult. As such it's time I start asking myself some big picture questions like what my career path should be and how do I envision my future?

As accustomed as I am to daydreaming, I find myself at an absolute loss attempting to answer those questions. Sure I can fabricate the glory of being a successful entrepreneur or doing groundbreaking research in my head, but there's no Ambition to accomplish them, there's no subliminal interest or excitement in learning or growing my experience and knowledge in something. I can fall in love with the concept of learning economics or environmental sciences, but is that really something that interests me? The line is so blurry, has anything ever interested me?

I'm so accustomed to tackling one day at a time, I feel like my brain isn't wired to think about the future. School and college were tough enough on its own let alone give me the bandwidth to understand my strengths or interests, and now I fear I've begun this discourse in my head too late.
