Positivity undoubtedly has an effect on success. As Paralympic medalist Bonnie St. John pointed out, pessimists are often right, but optimists have a better chance at being successful. By incorporating optimism into your day, you not only give yourself a better chance at succeeding, but you also foster an environment of success for those around you. Just like muscle, optimism can be cultivated. Through one of the methods Bonnie mentions, try boosting your optimism levels. You might be surprised by the creativity and innovation spurred by your newfound mental state!
