【参考译文】When we are stressed, depressed, upset, or otherwise in a negative state of mind because we perceive that “bad things” keep happening to us, it is important to shift those negative thoughts to something positive. If you start with one small, positive thing and repeat it during the course of your day, you will begin to move into a more positive situation. With practice, you will find that over time, you will change your outlook and choose to be happy, irregardless of the events around you.
