Well from my experience:
i) Pack everything else away that will sidetrack you.
ii) Have a point in time that 'x' needs to be done by, for me and the Zed table, it's always been trips across county where I need to take the table to play.
iii) Don't overstretch.
iv) KISS (Keep It simple, stupid!) Linked to the above.
v) Do post your WIP up somewhere, it does give you that little bit of a push at low times.
vi) Plan, plan plan: It will end up a glorified mess if you don't do the planning time.
v) Enjoy it!
Hope this helps, oh also this was all before I had twins so most of this now goes out of the window in the 18mins a week I have to my self when not sleeping/working/changing/feeding etc...
