Intervals -- that simple state of motion where one starts slowly and then speeds up. Recover slowly and then speed up again. Repeat, and repeat as the body learns to produce energy and withdraw as much fuel from our muscles as it can.

I suspect my gray matter operates in the same manner. I seem to be the most productive when I can concentrate, walk away, concentrate, literally run away, and then back at it again. I have always enjoyed multiple projects and hate monotony. Variety, thinking, and movement. Time to recover.

I am several hours into a new job application. Just a little something to help protect me as I get ready to go into business for myself. I am in this research mode which could literally last for weeks if I truly had the time. Luckily for my kids, I do not!

It will be a very merry Christmas, I suspect.
