You've got the power to let go even if you don't realize it yet. Try easing your grip just a little on monday and see what happens. You will soon see that whatever you thought was so crucial turns out to be just another thing, freeing you up for something way better. By the end of friday night, you'll have met someone who gives your mind a big spin and sets you off in an entirely new direction. Go with it. Your stubbornness over the weekend might come across as ego to people who don't know you well.
