When I retired, I pulled out my old college bike, 1974 UO8. It had sustained many moves across the country, and some poor storage conditions: under decks, in basements, garages, knocking around, and whatever. When I finished restoring this bike, I found out I had a bike that was way too big, and on the basic side. So I looked for another project.
Along the way, I sought out like minded individuals, to broaden my knowledge of bikes and components, and gain wisdom.
Now here I sit, well over 300 bikes done, and another 100 or so in the backlog. Oh, how things have changed.....
Now over five years into retirement, I have learned to do those things I enjoy doing (like working on bikes) and avoiding those things I did not care for (like company politics).
If you do the math backwards, you will find I was able to retire pretty early, thanks to some luck along the way, and a plan since 21.
