I expect people to be able to do their jobs competently. If I reduced my expectation of that I may be less disappointed, but I just wouldn't engage in health services so I don't think I'd be better off.

Expecting more from myself doesn't work when I'm exceedingly frustrated that I'm not immediately better because I'm too unwell to do the things to make me better.

I think this would work for people who shirked personal responsibility and blamed others a lot, but it's highly unhelpful and potentially damaging to those with limitations, trust issues, have gotten used to people letting them down or abandoning them and perfectionism.
