This is one of those lists where it's ruined by the author's compulsion to make it impressively long. As a result it's filled with things that you're obviously allowed to do ("Ask questions online", "say I don't know", "give to charity", "quit your job") which make it more difficult to find the small number of good ones ("Hire a researcher").
It means that overall the list is quite pointless and low quality.
