How to be a man with a heart and a mind?

Don't show your emotions. When you meet anyone, smile politely, talk less nonsense, be concise, be calm when things happen, rationally analyze the pros and cons of things, be alert to everyone, and tell seven points of truth and three points of lies when you lie. This will make cheating easier. Usually, try to help people who have nothing to do with you in small things. These people are very helpful at a critical moment. Read more and think more, not let you read online novels. La Roche, the art of speaking, one-minute eloquence training, the advantages and disadvantages of human nature, guiguzi, imperial tactics and so on. Simulate conversations with people around you in various situations at ordinary times, and choose the best dialogue to write down so that you can say it when it is useful in the future. It is best to occupy the moral high ground when quarreling with others. You can pretend to be poor and don't exaggerate your acting skills. The truer the better. For example, if someone asks you to give up your seat on the bus, you get up and pretend to be lame. Don't stand like this. The effect is quite good. Speak softly, hide the dagger in your smile, give people a powerful deterrent, and you will succeed.
