Negative focus depletes your energy. It works its evil magic by dissipating your power bank so that you spend so much time and effort considering “irrelevant” stuff.
Okay, so they hurt you deeply? How does spending a whole hour replaying it change anything? You wish you could give them a piece of your mind, right? How does that solve anything? Maybe you’re planning your big revenge, yeah?! How does that make you better?
Okay, now, drop it! Let it go. Focus on the positive stuff—on the things that can make you better; things that will make the world better.
Negative focus will burn you. Drop it like it’s hot!
