Your disposition is a personal choice. When you wake up feeling bad, you can choose to push that attitude onto others or you can choose to be happy. You can decide to be in a better mood or hang on to that bad one all day.
If someone bumps into you by mistake, you can let it make you angry, because you woke up crabby. You can also choose to smile and let it go. When you spill your cup of coffee, the last of the coffee in the house, you can growl at your family or go get coffee with a whistle out the door. If you get wet in an unexcepted rain shower, you can let it ruin your day or you can dance in the rain.
On this 100th day of 2021, in the midst of a Florida thunderstorm we choose happy.
