As a mechanic in the National Guard we spent the lion-share of our time performing PMCS (wikipedia link) Preventative Maintenance, Checks, and Services. It's the act of inspecting and re-inspecting equipment at various intervals. It's a good habit. Heck, it's a great habit. It's like cleaning the bathroom every Sunday, and inspecting the drains every month, stuff like that. And one of the stages of entering adulthood is the transfer of these tasks from your parents, to you gradually. It's how you define what kind of household you are going to have as an adult.
The second idea is the negative side, how constant maintenance prevents you from your mission. The world throws so much rifraff at you, too much stuff to process, and it all wants your constant attention and upkeep. You must decide what things to worry about and what not to worry about. You get hooked into a dependency hell (wikipedia link), eventually chasing things you have no interest in, but need, "The constant maintenance of his life, prevented him from living it."
So I guess you could say the poetry set is about striking a balance, or you could say I'm a beach ball since I kind of just made all that up. Enjoy! -Joel Lueders
