Power Living. It means living on your own terms. It means living without the internal voices that say BUT. "I'd like to (blank), BUT...", or "I wish I could (blank), but", or "I wish I was...", "I wish I had...", "I want to...", "I would...", BUT. It means instead every day confronting the reality that is your life, with all of its pressures and constraints, and believing, "Reality being what it is, this is the experience I am CHOOSING from among all of the options that are available to me".
RV Power Living. It means Power Living in an RV. (Actually motorhome, to be more accurate, RV for short.) Specifically a functioning, livable, drivable RV that isn't stationary in a park somewhere, permanently connected to the grid (because then you just have a cramped house with cheap rent, which is a different concept altogether), or a once-in-a-while getaway vehicle that you use for the occasional vacation cruise while maintaining a permanent domicile to temporarily escape from (which is also an entirely different concept).
