I'm glad that things worked out for the author but this is just generally not great advice for most people.

As nice as your manager is, even if they have your best interests in mind, they ultimately answer to someone else. And that means that even if they don't want to, they can f*k you over with minimal notice anyways. There's a power imbalance there.

Certainly don't be a dick about leaving and burn a ton of bridges... but the standard 2 weeks with professional and minimal responses is the way to go.
