I don't have a 10 year plan, but back in 2006 I started a 5 year plan which is progressing reasonably smoothly. Not terribly detailed, just key goals that needed to be achieved within certain timeframes. Not a plan, more a time-delineated checklist. There have been occasional inevitable hiccups along the way, but also unexpected areas of progress, so it all balances out. Essentially, I got fed up with the dismissive way I was treated by the government and the public sector organisation I work for, and began planning my exit and change of lifestyle to a more laid-back portfolio-style career. To facilitate this, I've started side-businesses in my spare time and arranged my financial affairs so as to allow me to retire from full-time work in 2011. The market downturn from about summer 08 until spring 09 spooked me a bit, but things have recovered well enough now to be back on track. Just got to keep other things growing over as planned the next 18 months and the plan will come to fruition. Fingers crossed!
Social/relationshippy stuff I don't plan though; that I leave to the winds of fate.
