I have lived a great deal among grown-ups. I have seen them intimately, close at hand. And that hasn’t much improved my opinion of them.” ~ Antoine de Saint-Exupéry

Emotional maturity is a difficult thing to measure. We can’t quantify it, or even describe exactly what it is. But we know it when we see it.

Many would say a person’s emotional maturity lies in their reactions to adversity and pain. Yet success and pleasure also serve to reveal a person’s ability to cope with their own emotions. We can observe how some rich people are charitable and helpful, while others are covetous and greedy. Similarly we see how some poor people are optimistic and hard-working, while others are self-defeating and without hope. People’s responses to circumstances vary greatly, just as emotional maturity varies.

Below are Five Traits of an emotionally mature person.

1) Ability to Love

Opening ourselves up to love, whether it be romantic, platonic, or familial, is an act of bravery. Making oneself vulnerable to both rejection and reciprocation is a sure sign of maturity. Young children can love without maturity because they have yet to be hurt or rejected. Hence why teenagers often close themselves to love — out of fear of loss or rejection. Once most people reach a mature age, they will have been hurt countless times.

Only an emotionally mature adult will be able to accept these rejections and pains as realities, and continue to open up and invite in intimacy and love to their lives. Most people are not so mature, and thus become jaded and cynical. They see love and intimacy of all kinds as childish and naive. But I would argue that closing oneself to love is the childish action. It’s the easy way out. It requires no bravery, no vulnerability, and no emotional maturity.

2) Willingness to Set Boundaries

It’s not easy to set boundaries. To do so we must speak out in times where it’s more comfortable to stick to the status quo. Life often presents situations where we can either let our integrity be eroded, or assert our own standards and boundaries. Choosing to set boundaries may lose us friends, or affection, but it will grant us immense self-respect. It prevents problems from developing into something much more damaging down the line.

But emotionally immature people aren’t comfortable setting boundaries. Rather than nipping interpersonal problems in the bud, they let them develop into full-on disasters and heart-breaks. They often get sucked into cycles of abuse or mistreatment. You’ll be able to spot an emotionally mature person by the quality and integrity of their relationships. There will be little if any unspoken tension or aggression. All that needs to be said, will be said. Even if it costs the relationship. An emotionally mature person operates under the belief that if a relationship violates their personal integrity, it’s not worth having.

3) Open-Mindedness

In modern times, nearly everyone claims to be open-minded. It’s become an attractive label, and a compliment. But it’s a trait few people actually possess. Because real open-mindedness comes down to one thing: the willingness to accept that you’re wrong. Many who claim to have an open mind really only have open ears. They’re happy to listen to new and challenging ideas and view points, but they internally reject all of them. They have barriers inside that stop new perspectives from actually effecting their notions about the world. These people will smile and nod as you share with them or challenge them, but their eyes will be blank and emotionally unresponsive.
