I picked up one hobby as an adult, "reborning dolls" which means taking rubber dolls, painting them with heat drying paint, rooting hair - making them look like real babies, at least in the photos. I painted a doll and was rooting the hair when my mania stopped. Figured out I hated doing it. I had spent almost a thousand dollars on the hobby and never touched it again.

For buying things... I had to have leather seats so I bought a new car - same brand and model of the car I had except one year newer and a different color. It never occurred me to that I could just have the seats recovered.
