If you wanna be mature, you have to act and behave in certain ways, think differently from others and also embody some various traits that will differentiate you from others. Some steps that will help you behave mature are here below...

STEPS:

ALWAYS BE CALM:

Being calm here means that you shouldn't overreact. For instance, if someone tends to hurt you by his/her actions or words, don't take action immediately. Just stay calm and think of the right thing to say or do. In the process of staying calm, something reasonable will get into your mind, then you'll know the right thing to do. Otherwise that, if you react so fast, you may end up doing things that you will later regret. So always be calm.

ALWAYS THINK BEFORE SAYING ANYTHING:

If you say anything that just gets into your mind, you might end up saying things that you may later regret saying them. So always think before you talk. Don't always talk because you feel like talking, Always talk because you have something meaningful to say.

DON'T JOKE AROUND TOO MUCH:
Sometimes joke can go a little too far. So mind the way you joke around with people and also mind the people you joke around with.

STOP BRAGGING:

It's looks immature when you start bragging of what you have. So stop the brag and be calm.

ALWAYS BE CARING:
Try caring for people /family members, treat people the way you'll like others to also treat you, show them much love and care.

LEARNING FROM YOUR MISTAKES:

Mature people are those who admits, learn and takes corrections from their mistakes. But immature people don't take corrections easily.

DON'T LET WHAT PEOPLE SAY OR THINK AFFECT YOU:

It's childish wasting your precious time thinking of what people do say or think about you. Always try not to give a damn about what people say at your back.
