In a certain way, maturity in general, it is not that we reach maturity in one thing and then another, the human being reaches maturity when he/she makes the decision of which path to take for his/her life in the future.
We know when another person has matured if we observe internal changes in his personality that are influential in his exterior, since we notice that he constantly changes his perspectives, assumes responsibilities that he did not assume before, in general we notice a personal growth, this generalized maturity is accompanied by a maturity in his emotions, since it is impossible to mature completely if we do not know how to control our emotions.
If what we want is to mature in life and in our emotions the first thing we must take into account is to be humble, this implies that we should not underestimate people to think that they are ignorant and know nothing, on the contrary we can receive great advice from the one we think the least.
When we are mature we maintain positions rooted in our own ideas and interests, we maintain these positions, we defend them and we explain them in the sense of why they are defended, therefore everything we do should not be to please people, but to educate them and try that what we say ends up generating a good for themselves.
Since we are born we are taught what we long for, we are taught the prototype of a famous person and examples to follow, and it is not that it is wrong to be like someone else, however we can be like other people who are a good example for our society, but always with our personality, we should never want to imitate someone else if to mature emotionally is what we most want in our life.
