Peter Drucker is considered the father of modern management. This book was originally published in 1967. It’s *remarkably* well written and lucid. And, of course, packed with Big Ideas on how to optimize our effectiveness. We cover the 5 key practices/habits of the effective executive: time (first things first; second things never!), contribution (what can you contribute?), strengths (make yours productive; make weaknesses irrelevant), concentration (the secret to effectiveness), decisions (boundary conditions help).
