Jump in the car and start driving with no destination in mind. Perhaps some places in mind but not time table for getting there. I live in the northeastern us and I'd love to visit the south, the Cumberland Gap and Blue Ridge Mountains. I'd then head west. Most stops would be natural wonders.
I've always thought there was some magic to working on cars but as I've been tinkering I've learned there isn't. It takes time, patience and persistance. I'd like to work on my truck, and wife's car, more. I enjoy solving mechanical problems and figuring things like that out. Of course I'd read the manual but there's a difference between reading the manual and actually doing it. While doing this work I'd like to simply enjoy it, not get stressed when things don't go right or worry about finishing by a certain time.
Build a garage or barn in my yard to follow through with working on cars and use to work on all kinds of stuff. I feel like I've missed the deadline for that one, I chose a profession I love but money is always tight. Perhaps I'll find a path that allows that to happen.
Visit Europe and tour ww2 battlefields. I don't celebrate war but I'd like to visit the places I've read about and try to understand what the soldiers went through. I'd start at the D day landing beaches, see the Hurtgun forest, the bridge at Remagen and Bastogne.
Chickens, that's another one. Very attainable but a big commitment to me. I'd hate to lose them to predators or the weather. It would be a hoot to work in the garden with a flock or 5-8 chickens following me around.
