I think the last paragraph of this post is your answer
Cook good food, take the dogs for a walk, value the opportunity to have a rest after work. Perhaps create a special time of the day when you actually play with the dogs as well as walking them. Maybe a ball in the back yard or some other fun thing, you need to laugh and play with your dogs to get your mojo back.
Do this until you feel impatient to get on with the reno, then you are mentally ready
For the past month, we have done nothing. NOTHING...and I love it.
We get up when we wake up.
Have breakfast, lunch and then supper.
In between we fill the hours playing on our netbooks, watching mindless fluff on tv, because it is entertaining. Playing a game of scrabble.
Looking for eggs, picking food from the garden, and preparing meals from scratch.
We have another month of this, and then it will be 4 -5 months of non-stop work, on our properties, in Canada.
While doing that, it is great...I love it.
When that is over, we will be exhausted, and look forward to the relaxation of returning to Australia.
Whatever you decide to do...do it because you want to
