I think it is good to have direction for your collection. When I fell in love with the simplicity and elegance of bicycles, I sought out to purchase everything I deemed nice. Over time, it became clear that the money and time I spent provided no clear direction in personal cycling tastes.
In the past few years my purchasing of bicycles, components, and disposables has lessened. It has been easier for me to follow a distinct path and not just crowd my rooms with whatever is the nicest. Fine English bikes and American handmade for me! I tell my SO I will sell off all my Italians, Belgians, French, and the likes one day… one day…
