Warning: Do not attempt to follow these tips without proper medical supervision.
When your celebrity surgeon tells you that your ego is a tumor that needs to be removed, just nod along while secretly planning a way to sneak into their OR and perform the removal yourself.
But seriously, have some sort of conversation, like:
"Uh, yeah, sure, I'll, uh, get right on that."
Start pretending that you're taking the recommended 6 months off to "recharge" and "rediscover your inner child" while secretly Googling "How to make a decent facelift on YouTube".
When asked about your "recovery plan", just say "Oh, yeah, I'm gonna be, uh, volunteering at a local animal shelter... and also, uh, practicing mindfulness."
