Tell yourself that it’s already broken. Tell yourself that you’ve already lost. Tell yourself that the person whom you are about to deal with is a total dipshit asshole moron. Tell yourself that you will eventually get divorced, hell, you’re already divorced and will probably never get laid again. Tell yourself that it’s already over and there is no point in expecting it to turn out all right in the end.
Then, you’ll be pleasantly surprised if anything ever works out in your favor. But, you will never be disappointed.
Have a nice day.
