Inspire yourself with a smile and positive reminders.
If you expect the worst, the worst will happen. If you let things bother you, they will. But if you smile, you’ll feel better. Studies have shown that putting a cheerful smile on your face can trigger a part of your brain that actually makes you feel happier and more optimistic about the present and future.
Also, feed your optimism with positive reminders. Write down short statements that inspire optimism. Put them in places where you’ll see them every day, such as on your bathroom mirror, the inside of your locker, and on your computer monitor.
