I retired at 59 about a year ago, so it's still pretty fresh. I can see now how retirement can cause killer stress for those who don't prepare their mind properly. It's all about contentment. We did it a lot differently from most by selling all our crap and living the gypsy life in a luxury 5th wheel. So every day is a bit of an adventure - but rarely stressful. We're now traversing life with a very, very light load, living comfortably and debt-free on <10% of what we used to. The only way to make the plan work is to lose the
desire to own 'things' (i.e., big houses, cool cars, expensive watches/jewelry, pole barns to put more crap in, etc., etc.) and lose the notion that you need to maintain your current lifestyle until you die. If you're getting your retirement advise from a financial adviser, you're doing it wrong!
Like they say, less is more. Way more.
