You already see your retirement vision. (I retired at age 52)More will come later especially on the physical side when you realize that part of your challenge will be to deal with your aging body. These goals are dynamic as time moves on and you change. That is why you will notice the changes when you review your goals over the years. You seem to understand this concept more than most people I have pitched it to.
Well, my goal is to retire at 52. At this point it is looking more like a decision than a goal - we already have enough money but waiting the few more years will let us get a few more things in order, few having to do with money.
And it's not just the aging body. It tends to enlarge too. We're already pretty active and getting more so as time permits. That's part of the reason for retiring - to have time to play.
