For me, getting set means clearing some space - both literally and figuratively. For my whole life, I have found it difficult to concentrate on a project when my surroundings are a mess, or if I have other projects looming. I hate loose ends.
So for the next day or two, I will be clearing up those surroundings and tying up those ends - either that, or table them to a later date.
Ah. I feel better already. What about you? What do you need to do to get set?
