First of all, where space is concerned, it is better to think big than small. The smaller you think, the worse you feel; the bigger you think, the better you feel. For example, thinking of Beijing is better than thinking of the sunrise area; thinking of China is better than thinking of Beijing; thinking of the world is better than thinking of China; thinking of the universe is better than thinking of the world. When you are depressed, think of the world and the universe, think of your own insignificance and the contingency of life, and your mood will brighten, and you will feel that there is nothing to be depressed about. Secondly, when it comes to time, it is better to think far away than to think close. The closer you think, the worse your mood; the farther you think, the better your mood. For example, thinking about a week is better than thinking about today; thinking about a month is better than thinking about a week; thinking about a year is better than thinking about a month; thinking about a lifetime is better than thinking about a year; thinking about thousands of years is better than thinking about a century; thinking about hundreds of millions of years is better than thinking about thousands of years. When you are not happy, think about a few years ago or a few years later, a lifetime or a few hundred million years, and think about the fact that you only have a few short decades to live, and instead of living such a depressing life, why don’t you just relax and finish the tens of thousands of days happily? Thirdly, when it comes to doing something, it is better to think about the end than the means. Think how to do the mood is not good; think why to do the mood will be good. For example, it is better to think why to earn money than to think how to earn money; it is better to think why to evaluate professors than to think how to evaluate professors; it is better to think why to be an official than to think how to be an official; it is better to think why to be famous than to think how to be famous; it is better to think why to be alive than to think how to be alive. When you are unhappy, think about why you do all the things you do, think about why you live to be happy rather than to suffer, and then do only those things that bring you happiness, and let go of those things that bring you pain and suffering, and you will naturally be in a better mood. Fourthly, in all matters involving other people, it is better to think of people you like than to think of people you hate. When you think of people you hate, you are not in a good mood; when you think of people you like, you are in a good mood. For example, it is better to think of your parents than to think of your leaders; it is better to think of your friends than to think of your coworkers; it is better to think of your loved ones than to think of your enemies. When you are unhappy, think about those who love you and like you; think about those who you love and like you. Think about how dear and lovely they are, and how good they are to themselves, instead of thinking about those who hate themselves or those they hate, so that the depressed mood can be cheerful and pleasant. Finally, in all matters concerning oneself, it is better to think of the advantages than of the disadvantages. Thinking about one’s own shortcomings will be in a bad mood; thinking about one’s own merits will be in a good mood. For example, if you look pretty, think, God really favors me, I was born so beautiful; if you are smart, think, other people spend an hour to figure out how I understand a few minutes, I’m really happy; if you live a long time, think, other people only live more than eighty years old, I even lived to one hundred years old, I’m really lucky. In this way, even if you are not beautiful, not smart, not big enough, not enough money, not famous enough, but there are still some better than others, so after thinking about it, the mood may be better. Although life is often not as good as nine or nine, but as long as you can often be so to adjust themselves, you will be able to often maintain a good mood. Even if some people say that this is just a Q’s triumph of the spirit, I would rather do this, after all, it is still better than moping through life.
