Forget everything you’ve planned.
Ask 500 people in your field what they would like to change in the future. Now launch your community with that objective.
Your community will have 500 owners. 500 shareholders. 500 people who have helped craft their vision of the future and put themselves forward to be part of it.
They feel they have contributed. They feel appreciated, effective. That’s 500 members who will join when you launch. And tell many others.
It’s a lot of work, but it’s worth every member.
