When I am dealing with people I like, in businesses I find stimulating (what business isn’t?), and achieving worthwhile overall returns on capital employed (say, 10–12%), it seems foolish to rush from situation to situation to earn a few more percentage points. It also does not seem sensible to me to trade known pleasant personal relationships with high grade people, at a decent rate of return, for possible irritation, aggravation or worse at potentially higher returns.
