In a UK small business the CEO is usually also the head of sales, the credit controller and the person who unlocks the building. This list is built for that job rather than for the one the title implies.
The selection leans towards allocation: where to put the next pound and the next hour, what to stop doing, and how to tell the difference between a business that is growing and one that is merely getting busier. Those are the decisions nobody else in the company can make for you.
Also included, deliberately, are one or two on the psychological side of the role. The isolation of it is a practical problem, not a soft one — it distorts judgement, and the books that name it are more useful than the ones that do not.
