Sharing this article from Mr. Collins’ website because I admire both his and Peter Drucker’s work.

#9: RUN LEAN
One of Drucker’s most important insights is that an organization is like a biological organism in one key way: internal mass grows at a faster rate than external surface; thus, as the organization grows, an increasing proportion of energy diverts to managing the internal mass rather than contributing to the outside world. Combine this with another Druckerian truth: The accomplishments of a single right person in a key seat dwarf the combined accomplishment of dividing the seat among multiple B-players. Get better people, give them really big things to do, enlarge their responsibilities, and let them work. Resist the temptation to redesign seats on the bus to specific personalities (except for the exceptionally rare genius), as this will inevitably create seats you don’t need. “The fewer people, the smaller, the less activity inside,” writes Drucker, “the more nearly perfect is the organization.”
#10: BE USEFUL
When I was just 36, Tom Brown, editor for Industry Week magazine, somehow got Drucker to invite me to visit with him in Claremont. I clicked on my answering machine one day after teaching my classes at Stanford, and heard a resonant Austrian accent: “This is Peter Drucker.” When I called him back to arrange a day, I asked if I should schedule with his assistant, to which he replied, “I am my own secretary.” He lived a simple life, no staff, no research assistants, no formal office. He typed on a clickity-clack old typewriter, set at 90 degrees off of a small desk, working in the spare bedroom of a modest house. He met in his living room with powerful CEOs, sitting not at a desk, but in a wicker chair. And yet with this minimalist method, Drucker stood as the most impactful management thinker of the twentieth century.
