This is another big one! If you make it look too hard, no one will join you. In everything you do, ask yourself if you are making it too hard. Are you making it unattainable? Are you making it appear too difficult for the average person to do what you have done? Are you holding everything to such a high standard (formal teaching, extravagant make and takes, big vendor events with all the trappings) that you intimidate others to assume they can never do what you do?
If the answer is yes, you are losing leaders. Make EVERYTHING duplicable.
