It’s easy to say yes—people like you when you say yes to the things they want or need. It’s tougher to say no, but sometimes saying no is just the thing you need to feel happier. Is someone trying to push you into doing something you don’t have time or the desire to do? Say no. Is someone trying to make you bend on a boundary you feel you need to stand firm on? Say no. Is someone trying to dump a project or task on you? Say no. If you have a hard time saying no, try this: stand in front of a mirror and practice saying, No, it’s not possible, and then turning and walking away. You never again have to give in when you know you don’t want to do something or when you know something is not a good idea. Practice until saying no is as easy as saying yes. Saying no is a powerful tool in your game-of-life chest.
