Welcome to the club!
Or, the disease it becomes...
there is a sense of satisfaction of doing it yourself, and depending on your tools and inclination, it can take less time than waiting for someone else to do it. I hope to keep doing it a long time.
I have the 3 cars between my wife and I, but also support 4 kids' cars, depending on the relationship with their parents/step-parents, etc.. I don't plan to always do theirs, but for now would rather do it myself for cost reasons and to catch what others might miss before problems happen. Just keeping an eye on fluids, hoses and belts goes a long way.
