People who fault themselves for their own failures annoy you? Gee.

"I want to do that, but I just don't have the willpower" used as an excuse not to try would get annoying quickly. You don't really want to do it; you just want to signal like you do.

Faulting yourself is useful iff you subsequently attempt to fix yourself. Otherwise it's probably counterproductive.

Well, generally they tend to fault themselves and others. Really, it's more the faulting of others that annoys me the most.
