I wrote a similar post to this about 3 years ago, and I think my path is already quite different from what I'd envisioned there. Which is why these kinds of questions are so fun!
This question is also hard for me because I don't really know where to see myself in 6 months, let alone 10-15 years, but I'll try anyway.
10 years: Kickin' it in Cali. In 10 years I'll hopefully have a super swanky place in a really nice neighborhood. Cool furniture. Maybe a birdbath. I'd like to have landed a series regular role on a successful sitcom - something that runs for 6-7 years and gets picked up for syndication. Maybe I'll have "sold out" and become an advertising spokesman for something like Apple or Hot Pockets. I think I'll still have a scooter. I really like my scooter. I think maybe there will be some non-profit organizations involved in my life. Something educationally themed. I'll volunteer at schools and do plays at the children's theater. Hopefully there will be a wife and a couple of little ones in the picture by then, but again - anyone's guess. If there isn't a wife, there may be a cat. Hypoallergenic cuz my mom's allergic.
15 years: I'll be almost 45. That kind of blows my mind right now. I don't even know what to project. Successful career, maybe by that time I can move back to Utah and work from there like the guy on Modern Family. I hope I don't have a bad haircut. I also hope that I've managed to keep myself grounded and that I've never been called to be a bishop.
