Unfortunately, regardless of how much I want to, I can't imagine a best-case scenario of where I'll be in 2020, there is just so much that I want to do. Hopefully I'll be working on something interesting, fascinating and ground braking. But more importantly, I hope I'll be happy. Saying anything other than this would be a lie.
But I hope that when you contact me in 10 years, I'll be able to say that I'm doing something that makes me happy and I wouldn't want to do anything other than that. And maybe, just maybe, what I do will make a difference in the world.
