Nope! The message was crystal clear. He even said the words, "get your CFI"!
And yet you still didn't take it to heart. You got the counsel, and you let it go.
Can't work well with others in the cockpit? A professional cockpit is not for you. You want to carry passengers, but don't work well explaining things to those with little or no aviation experience? Your goal is to fly tourists over the Grand Canyon?
When I flew the ditch full time (two years), virtually everyone I knew with whom I worked held a flight instructor certificate. What an amazing coincidence, isn't it, that everyone had experience as an instructor? You're different, though, aren't you?
Some pilots just don't make good CFIs! Accept it, move on, and be happy that that's one less pilot you need to compete against!
As a primary instructor you'll never be in competition with me, so personally I really don't care. You may be one less pilot in the work place, however, because without your willingness to learn to teach, you may be stopping your career progression in the early stages.
So stubborn, yet so convinced you know it all.
