For me, the key was, stick to the task at hand, and not get sidetracked by all the sub-systems within the office that need organizing. I can deal with the photos that need to be sorted as a separate task. I can completely straighten out my library later. Also, I did it all in one day - with breaks - so I wouldn’t lose the momentum.

Finally, I began the job with the proper tools: A big wastebasket, bags for recycling, plastic bags to dump the wastebasket into when it was full.
