I love Gretchen Rubin's recent suggestion to practice reverse gossiping, saying something complimentary about someone behind their back.
The practice increases positivity in the world.
The phenomenon of Trait Transfer means that people associate you with the traits that you talk about. So, if you say other people are smart and creative, they believe you are, too.
Your thoughts affect your perception of the world. When you notice the positive, you start feeling more positive about everything.
Today, make a promise to not talk negatively about people in your life.
Your boss micro-managing you? Talk about what you do appreciate about her. Your in-laws driving you crazy? Think about how they shaped your partner that you love.
Experiment with shifting your thoughts to shift your reality.
