You won’t feel the change from newbie outsider to invested insider, because it probably doesn’t happen in a single moment. But you will feel the recognition of it having occurred. You will find yourself facing some change to the status quo, a status quo that once felt both alien and inevitable, and the status quo will suddenly seem fungible. You will feel things about the change, including, possibly, resistance. And in that moment you will know that you have become the status quo.
That’s not bad, necessarily. As with almost everything, representing the status quo comes with both responsibilities and benefits, risks and rewards.
