That's my goal. In two years, I'll be 62, and able to double-dip, which will pay the bills. If I still enjoy where I'm working, then I'll keep doing it.
However, my youngest son will be entering HS. He'll be taking a heavy load, i.e. nothing but AP courses to go with athletics, band, and scouts. During the day, I'll be working on my wine hobby, perhaps I can turn it into real money (website, marketing, who knows). When my son gets home, I can be there to watch him and my grandson, and help out on homework as need be.
I also look forward to going on road trips during good weather, such as visiting my sister in Reno, with a 2-3 day stop in Kanab, UT. I can then visit several wineries in the state at my leisure. Just having that flexibility gives me a real charge.
