I once worked with a colleague who always put a block in their diary across Monday morning. No one could disturb them, no phone calls got through. The place could be burning down, but they wouldn't leave their office. The door was locked and bolted from the inside (not quite, but you get the idea). in the diary for every Monday morning, it simply stated two words; "Strategic Thinking". On Monday afternoons, they were always in a foul frame of mind. Asked how the morning has gone, the reply was always the same - "dreadful, I've not been able to do anything"! The colleague, made the same mistakes every week for nearly forty-seven weeks a year. By simply blocking time out and calling it the thing they wanted to do, they honestly thought that it would happen, they would be able to think strategically. That's simply not how it works.
