National I Want You to be Happy Day is observed annually on March 3. This day was created as a day encouraging us to do something to make others happy. Putting a smile on someone’s face tends to put one on ours, too. It’s actually quite limitless. A flower here, a silly knock-knock joke there. Buy the person’s coffee standing in line behind you. Remind your kids how much you love them. Leave a sticky note for a co-worker telling them to have a spectacular day, a happy day.
