5 years later I achieved that goal.
My plan was nowhere near the detail of this but there were steps along the way. Things changed a lot, and not everything was done in the order I originally planned.
With that said, having a clear vision of where I wanted to be and loosely how I was going to get there meant that I could turn down opportunities that may have led me astray, or which didn't further my career/life goals.
YMMV.
