Maturity is such a commonly used word that sometimes it is difficult to understand how relevant it is in communication whether at home, with friends or at work. Here are some tips to be more mature.

1. A mature person has integrity. Basically your yes is yes and your no is no. integrity is a difficult and sometimes confusing word because a lot of people view integrity differently. Some people misinterpret it to mean that you are arrogant or insubordinate but it is just sticking to your guts and making sure everyone involved or related to that situation understands your well defined parameters which is very necessary when dealing with people.
2. Be responsible. One must take personal responsibility for every circumstance good and bad. That is the only way to earn the respect of people around you. Initially, people may reject it but in the end they will respect you.
3. Good communication skills. Being courteous at all times when communicating or expressing your views on a subject will go a long way to show your maturity. Also being clear and direct about what you want or require is also a good way to show your maturity. Being direct, emphatic and clear is a good way to go. So don’t lose steam when that seems seemingly problematic.
4. Being respectful of people’s feelings and sentiments.  It is absolutely important to be respectful to others whether or not they are respectful to you. Always keep that pleasant demeanor and you will be great!
5. Discipline is also a great sign of maturity. Exercising self-control and understanding what to do and when to do it is also a useful trait to cultivate.
