To me, bikes are fun. When I'm riding I'm out having fun. When I ride my old Navigator (now pretty much only when my wife wants to go along too) it is fun. When I ride the road bike it is fun and much more athletic (can't believe I'm using that word with something I do...) but it is fun too. Ride for fun. Ride for profit if you can counter the price of gas along the way (hard for me). Ride to ride because riding is FUN!
