Edit: does this help?
The basic idea is that to solve a problem, you must take the right kind of action more often. Yet what compels us to take these actions when we are not self-motivated? Functional does, by taking it social.
1. Identify your problem or interest
2. Join or create a group whose topic is that problem or interest. The group may provide seed activities. Each activity has a target frequency (e.g. once per week)
3. Optional: add more activities you'd like to do more often
4. Tell the Functional when you do those activities
5. Everyone in your group gets to see how you're doing. Nobody gets to see what you're doing.
6. If you fall behind on an activity, you'll receive a message to do that activity from someone in your group.
The system is designed to be persuasive so that those simple messages (and other stuff) are as compelling as possible.
