First, whether there are good friends with good conduct can lead a person to a better life, but bad friends will affect a person's future development. Making friends, whether it suits you or not, depends on this person's personality. If your friends always advise you to smoke and drink, and always take yourself to some bad places to experience yourself, then such friends should run away quickly, that is, friends who drag others into the water. Therefore, when making friends, if the other person is clever, principled and has his own attitude in everything, then it shows that this person's character is ok, he can make friends and he can make friends in the future.
Second, friends who can benefit each other should not be too selfish, but they should not be too bullying. If you say that you have made a friend, but you only know how to eat and drink every day, there is no thank you. It looks friendly on the surface, but it always takes advantage behind the scenes. Such a friend is very humbled to make friends even if there is not much problem with his conduct. Therefore, when making friends, we must pay attention to mutual benefit, at the very least, we will not take advantage of each other, so that we will feel more comfortable during the conversation. Moreover, if most friends really treat themselves, they will not always want to take advantage of small things, so this is also very important.
Third, friends should be treated rationally. Of course, some people have a stronger Jianghu atmosphere and always want to do anything for their friends. Much like the plot in the novel. But everyone has their own ability to solve problems. Sometimes, don't interfere too much in friends' lives, lest you do bad things.
