Here’s an excellent quote about business execs I just came across from management expert, Peter Drucker. It could certainly apply to IT and security professionals just the same:
“The most common cause of executive failure is inability or unwillingness to change with the demands of a new position. The executive who keeps on doing what he has done successfully before is almost bound to fail.”
…in other words, if you keep doing what you’re doing, you’re going to keep getting what you’ve gotten.
