I learned that having a completely clear desk makes it much easier for me to think and focus, and makes me want to sit down and work.
This is true even if the desk is clear only because I have methodically swept the contents of the desk surface into a big bag in advance of showing my office to a visitor.
Whatever.
Jane's Lessons Learned 
Omg, Jane, I did the same thing! Go figure… However, I took the bag and moved my “office” to a great table on the enclosed porch. ( I am currently writing this on the porch.) The weather is great, 70 degrees, the pets and kids are a definate distraction, and my desk inside is now covered with sad projects. Moving back will be a bummer but more productive. The bag does not prioritize my work!
