It feels like you're defining "fun" or "enjoyable" differently than most people would.
Most people don't find their "fun" activities enjoyable all the time. Running can be fun, but it also is tiring and sucks sometimes. Practicing a musical instrument isn't the most enjoyable, but playing in a band and nailing songs is. Lifting isn't "fun," but excelling at a sport is.
Point being that not liking the boring parts of an activity, but still finding the activity as a whole satisfying, is something that most people would consider to be an activity you enjoy.
