I have seen the opposite personally - people who push optimism as less successful but cheerfully repeatedly making terrible foolish mistakes. From "I totally won't wind up homeless in LA if I move there to make it as a star with no acting education or experience." To "If I stay loyal to this horrible person who abuses me they will get better." Pessimists I have seen generally as more secure from planning for the worst perhaps to overkill extents but less happy. The snarky summary is "An optimist is a million dollars in debt, losing money every day and thinks it will get better. A pessimist will eventually have a million dollars, feel precariously worried about pending disaster while their true greatest risk is their urge to commit suicide."
