How do u adjust your mood?

I have already set long term goals, so I just try to realize them day to day, one day at a time, seizing opportunities when they come along, letting things go by when they do not contribute to long term goals. When things really look gloomy, I still look for positive aspects in the situation. I'm a firm believer in the saying that there's always a silver lining at the edge of the dark cloud: or that when you are at the bottom, the only place to go is up. The Chinese also believe that a situation of crisis is an opportunity. I subscribe to that. When something really upsets me, a trip to a bookstore or just looking at my books at home and leafing through the pages calms me down. Or, alternatively, going to a public market, sitting by a corner, observing people interacting with others. In short, it will take a lot to discourage me or to make me moody. But I will not stay discouraged or moody. Life is too short and too precious to waste. I readily spring back because it does not take much to reinvigorate me.
