Interesting question.
In case of charities, when you help the people how do you feel? If you feel joyous that you can help them, then you will not attract homelessness. Otherwise people like Mother Teresa would not be able to become so strong.
In case of shrinks, I think it is true.
Not sure if it is LOA or something else. In any case, all shrinks have to undergo psychiatric test before they can start. Plus, by definition, no person is 100% sane. So I imagine if you are psychiatrist yourself, you would always view your own actions with a magnifying glass.
