Not sure if this seems too random but I think that's what I like about OpenStreetMap editing: it's only a few clicks to improve the map and thousands or more people will come across it. You're changing the world in one of the literal senses of the phrase, and can do it from an armchair (doing quality assurance or using aerial imagery) or use it as motivation to seek out places near you that you've not visited yet. Maybe that's something you'd enjoy as well
