How to make yourself less naive?

The way to get rid of childishness is as follows:

I. Experience

Young people imagine life so smoothly because they don't have enough experience and deep experience. They always think that everything is very simple, very simple, but they don't know how complicated this society is. We can think of it this way. In the past, your experience was learning. Now your experience is working for others. Your experience in the future is to let others work for you. Therefore, experience is a good way to get rid of your childishness.

Second, the ability to live independently.

Youth is the best capital. Be independent while you are still young! Even if you suffer setbacks, even if you fail, you are backed by youth. What are you afraid of? Do you have too many setbacks and troubles? For a fresh graduate, don't think too much. Independence gives you a better sense of direction.
