Improve your attitude with a dose of gratitude daily. Studies have shown that 90 percent of people say expressing gratitude made them happier people and more than 75 percent said it reduced stress and depression and gave them more energy. Start by making an effort to thank people more often. Then advance to counting your blessings at least once a day for 30 seconds. Need some suggestions? Be thankful for your health, your food, your family, and your friends. Heck, thank your letter carrier even if all he brings is bills. He or she may be out of a job next month.
