You know how they say having a work-out partner helps with commitment to exercise? Having an Art-Out Partner (Buddy?) is really, really helpful. Knowing that someone else is going to show up and ring your studio doorbell gets you going. :-) Even if you choose someone who is not in your exact area, you can support one another and check in. Actually, cross disciplines works a bit better, because you don't have any elements of competition. One of my neighbors has done this for me - she's a photographer.
