There is one feeling that can be generated very quickly and that overshadows all negative thoughts. This feeling is gratitude. When you are troubled by your burdens, just think of three things you are grateful for. It might be a ray of sunshine outside your window, your last pay rise or just a good conversation. Try to really feel this gratitude. You will find that you cannot be grateful and frustrated at the same time.
