I love mini goals, they're pretty much the whole reason I can get out of the house these days. Set mini goals for everything and ignore the end goal. Then, once you get to the last mini goal, the end goal isn't so intimidating.

Some days my end goal is just to have a shower because it has been a week and, despite my irrational terror, I'm pretty sure I won't be attacked by a shark while showering. Other days my goals are bigger because my capacity to meet them is greater. I think the important thing is to keep making the goals though, and don't compare your goals to other people's goals, because you don't know what kind of equipment they're working with.
