Random thought:

If you became an individual, graduated from your tribe, and don't feel like you belong to any other tribe after that (assuming you want to be in one), become that tribe yourself so that others seeking it will find the blinking light and get lured to it, and also poke (not force) at those who wouldn't be in your tribe but help them reach it. People will most likely become part of your tribe that you've created (but its not dependent on you), given enough time, and even if no one joins it, you were at peace with yourself and had a blast =3
