Set up a new social media account that is a mirror or reflection of your normal account. The specifics are up to you. Mirrors reflect but also flip images. What would your account look like if you reflected it? Try to think less literally about this and more metaphorically.
What would be the opposite of what you post right now? Start a new account and post that. If you usually post quickly and often, try to become more methodical and slow about what and how you post. If you are usually very political, try to post things that are not as attached to politics or time on your mirror account.
