I was one of those guys that would pick a new hobby every year, buy a bunch of books and read up to a level of expertise and then spend a bunch of money (or physical energy) to reach a reasonable level of performance. Started with Golf, moved to WW kayaking, moved to building wooden strip kayaks, moved on to running marathons (ran 10,000 miles before i had to move on), moved on to training bird dogs, took up Mountain biking, moved on to road bikes (and broke some bones), took up surf kayaking, took up pistol shooting and reloading, took up scuba diving, took up snowboarding, fast sports cars, professional speaking, mountain hiking, photograhy, reloading for rifles, and thanks to COVID in 2020 took up cooking. In 2021 i finished designing, building and decorating my semi-retirement home (with a detachec office/reloading room) in the Texas Hill Country. Plans for 2022 are to rebuild a 1970 Datsun 240 Z.
I was very fortunate that my job had me traveling around the world (over a 100 trips to 30 plus countries) and that allowed for a lot of time for reading and critical thinking and planning.
The really amazing thing is that i am still married to the girl I met in 1975.
