Is the first place you wish you started.
Because then you wouldn’t have had to go through all that “trying stuff and failing and feeling like garbage about not having got it perfect before.”
This is true.
But now you know the first place to look next time, so now next time there will be a last place to look.
The Last Place to Look is based on where you are in figuring things out, each time you’ll find a new place to look last (translation: it can’t be avoided so stop giving yourself a hard time).
