Hearing this I feel slightly embarrassed. I have to admit I get an urge to go for a walk in the middle of any working day. Mainly because I get bored and want to clear my head. However, sitting down and just working when you need to work, although nobody is watching or forcing you to, is a textbook example on how to deal with resistance and a sign of true mastery. Sit down, get your ducks in a row and work. Simple as that and I respect it immensely.
