Why is it so much easier to believe negative outcomes and wishes unfulfilled? Even in a situation which outcome is 50/50, to believe it will end in my favour is more difficult than to believe it will end up not how I want it.
Is it maybe about insecurities? Not thinking you deserve anything good?

How do you deal with this?

If I ever get handed a task with crystal clear requirements I'll know I have somehow been transported to another dimension.
