I started a work diary and that helped me some keeping the "thread" and my own organization going. You can always take 30 seconds to write the time and what is being dropped (and where you are with it) and what picked up and do a little thinking about (get distance from) what you are going to do and give an estimate of how long it will take, kind of do a bit of personal organization of your thoughts before you jump up and actually "do" anything.

I also brought in a good book of quotes or daily "messages" or some other book I enjoyed a lot and did not mind re-reading, etc. and would take a few minutes to remind myself of good stuff while something was printing or before picking up the next thing, etc. I thought of things to do on my lunch half hour (go find where the library was, how to get a library card from the "foreign" library (I needed a letter from an officer of my company on letterhead); just drive 10 minutes down the road and note what was "that" way then drive back, the next day go the other direction, etc. I took some online classes too, and would do papers/projects based on work where I could or I'd read company/industry magazines we'd get and think about angles I could take to write an article for them or I'd just up my knowledge of the industry, check out other companies advertising in the magazine (one I liked so much I bought stock in the company and that made me a lot of money), etc.
