My answer is a bit more long-winded, but I guess that's the norm from me.
It's not so much as to where I want to be in 5 years, but rather, closer to 15 years.
In about 15 years, I'll be in a position where I could retire from my current job, and have some pretty nice benefits, as part of a package for having a certain number of service years, at this institution. At that time, I would actually consider having my own dojo, one way or the other. I would hopefully be one of the more senior people in the system, and have the knowledge and experience (and wisdom) needed to smoothly run such an operation.
I've thought about this for a while and asked myself this: Do I really want to spend the rest of my life constantly writing up grant proposals, begging the government for research dollars, etc? After having run into hostile reviewers along the way for my grant proposals (it really only takes one to tank your score and push you into the unfundable area), it does get tiresome having to hope that each time, you can get a fair review panel. Even worse, is that people who may not like you, will often times refuse to recuse themselves from the panels, even though they are supposed to do so...
Don't get me wrong; I enjoy doing research, and actually writing up my results is quite enjoyable. I also know that what I am doing does help the human race as a whole, and that there aren't that many people who can do this kind of research.
However, when the joys of research get polluted with politics and backstabbing to such an extent, that it's not a matter of wondering how much you'll get from a well-written, well-researched proposal, but rather praying that an ignorant hostile reviewer doesn't mess it up, then perhaps it's a sign. Maybe it's a case of "the grass is greener on the other side," or maybe it's because of the stress that comes with a funding drought. Maybe once funding becomes more fluid, I won't be entertaining such thoughts, but I do wonder...
It's not a matter of personal income. As martial arts instructors, we are here to promote the arts themselves as the primary purpose, else we wouldn't be doing this. I'm fairly comfortable in the amount I already make in the academic world (which isn't really that much), and as long as I can maintain that level of pay, then income wouldn't really be a concern.
The way I see it, though, I have a good bit of time to think this over, and in the meantime, continue to advance in the system, accumulating more knowledge and experience. When the time comes, I'll know that I can make a thoroughly researched decision. For now, though, I guess it's time to finish expressing those proteins...
