By life-long consistent hobby has been collecting hobbies. Learning how to do new things is a high for me. I can't stop! I get interested in something, fixate on it for a while and learn everything I can, then move onto the next thing.
After a few decades, I've racked up quite a list of skills. I'll add more detail as my time and attention allows. I could talk your ear off, literally for hours, about any of these. Tread carefully.
