"Resting on one's laurels"

[To rely on one's past achievements instead of working to maintain or advance one's status or reputation.]

This goes hand-in-hand with erecting monuments to one's self-professed achievements as proof of those achievements.

There are several people here and elsewhere (though they likely - and this is funny AND revealing - don't even know who they are), who have made, and are making a career out of "resting on their laurels", and each supposed effort they make to further their shaky status, is nothing but further erections in their life's-work of building a monument to their self-proclaimed prior achievements. (So they write a book, publish a website, author a "My Story" page detailing their "sudden enlightenment.")

"I am GOD realized (and you're not!) Here's what happened."
"I had an instant enlightenment in 1986 (and you didn't!) Here's my story."
"I am a yam and that's all that I yam (and you ain't!) Here's the glorious details."

Nothing but BRICKS in the monument, pushed into place by people who have nothing more intelligent to do with the rest of their lives than erecting monuments while resting on their laurels.

And, they actually think/believe/hope someone is impressed by all that.
