I just got back from my second trip to Florida in 5 weeks; this time with my daughters. I like working only 3 weeks a month. It improves my attitude. My sunny disposition lasts until about the third work email.
Selling bikes and parts before allowing myself to buy bikes and parts serves two purposes. First, the net cost of riding is reduced to only race fees and maintenance parts (maintenance parts do not count as an expense that has to be offset by selling something, in my convoluted way of thinking, unless I try to sneak in an upgrade under the umbrella of necessary maintenance in which case I force myself to sell something to make up for the additional cost of the upgrade over what was on the bicycle, unless the upgrade saves 1 gram of weight for every dollar spent, which was grandfathered in a long time ago. It's complicated).
The second purpose for this zero sum gain philosophy is to keep my inventory of bike stuff to a reasonable level. I know myself well enough to know I could easily turn into the crazy cat woman of bicycle parts. My apartment could become so packed with bike parts that I would have to make tunnels to move about and this would not bother me at all. I don't think I am materialistic but it hurts to sell my bicycles. Somehow they seem more than just stuff. My dad has the same feelings about vintage car parts. He will enthusiastically explain how Ford Designers used this little chrome trim piece on the 1965 Mercury Comet as a last minute fix to hide a body weld in the car’s rear quarter. I love his passion. I hate his piles of car parts.
