I'm sure you know the story of Scumbag Scrooge: Grumpy, kinda bad guy before and then transforms happy and fulfilled after.
Unlike the other 6 plotlines, Booker doesn't provide distinct stages to The Rebirth but rather some helpful components:
Our protagonist falls into some dark power or force (fear, greed, lust)
For a while, nothing really bad happens, they just live their life with all of their bad traits
A threat occurs, forcing them to be their worst self until they can't take it anymore.
The darkness sticks around until the protagonist is completely overcome
By some miracle, the protagonist realizes their mistakes and begins to change because of some catalyst.
Examples from popular culture:
How the Grinch Stole Christmas
A Christmas Carol
Beauty and The Beast
Theon Greyjoy (in the show)
Everyone loves a good redemption arc. I think it appeals to some darker side of us that is relieved that we can own our mistakes and better ourselves.
I know that's comforting to me at least.
The Rebirth is great for highlighting how things may have been bad, but they're better now. How your client or audience can feel their new reality, feel their new life after much discomfort.
Maybe your newest service offers a full organizational makeover with tips and trips to stay organized. You can frame this service as a rebirth: ditching old habits that hurt productivity and ushering in a new legacy of minimalism.
You can also use the rebirth has a way to tell your audience that you've learned something new, learned from past mistakes (this is so applicable to affiliate links).
Showcase how times have changed, old habits are tossed out and everything is new and bright and ripe for the taking.
