This is pretty much what I used to think. If it works out for you, then great, but I think you might find its unrealistic.

I suspect that your 9 year plan is an unrealistic, best-case scenario, that won't come to pass.

Also, 9 years is a long time to survive if you're miserable. I think you may find that at some point, your employer and coworkers notice it, get sick of working with you, and replace you with someone else that really likes programming. Like a lot. But right now, not N years ago.
