difference between being somebody and doing something (Boyd)

a fast bowler bowls fast bowls, but a person playing the game will attempt to take wickets one way or the other

(this is a sucky example. a fast bowler attempts to take wickets. presuming it is easier to bowl medium or slow , the hypothesis is that a person bowling fast is attempting to do a difficult thing, when easier options exist)

how about - managers exist to retain, and grow budgets, and only incidentally grow their divisions/projects/teams
