I wrote this for another hobby but it applies to bikes also I think.
Do not surrender to - what I have named - "grail emptiness". The feeling of meaninglessness and anxiety that can hit you when you have reached one of your goals. The emptiness and sometimes disorientation has its explanation.
Take comfort in the knowledge that collecting is not solely about the possession of things. It is as much, or more and for some, maybe to the full extent - about the quest. The research, the hunt, the journey, meetings, contacts - and the dreaming.
You are not alone in your grail emptiness. I would say we all suffer from it in different ways and forms. I tackle it by finding a new grail to covet and long for. Sometimes I alternate between hobbies to find new inspiration.
I found this some time ago and I think it is well put:
“The main thing is that I discovered that half the fun of owning a watch is, like the fulfillment of all desires, about the pursuit –shopping around is fun and ownership is the beginning of something, but also the end.” Jack Forster, Contributor, Forbes Magazine
