When the same thing isn’t any different

You own a bicycle. You ride and maintain it yourself for fourteen years. One day you ride to work and discover a problem. You put a band-aid on it and let it go at that. A week later you find another problem and you apply another band-aid. This goes on for two months, and you finally decide that you just don’t want to deal with it all yourself right now. You take your bike to the shop for more permanent repairs. Two hundred dollars gets you two rebuilt wheels, new rear brakes with a new cable, a new rear cassette and a new chain. The next day you ride your bike to work, for some reason expecting the bike to feel different.

It doesn’t.

It’s not that the problems weren’t fixed, it’s just that two hundred dollars didn’t buy you a new bicycle (even if it was a lot cheaper).
