When you center yourself, it's such a peaceful feeling. If you've never tried it, find a place where you won't be disturbed. Get comfortable, and breathe deeply. Visualize your heart center, and continue to breathe. You don't have to sit there for a long time, just a few minutes will help you to feel a lot better.
A Connection Stone that says Center can remind you to take a few minutes for yourself. The stones are 1.25" in diameter and are made in the USA from frosted glass.
