12 Signs of emotional maturity

1. Flexibility

You are able to see each situation as unique and you can adapt your style accordingly.

 2. Responsibility

You take responsibility for your own life. You understand that your current circumstances are a result of the decisions you have taken up to now. When something goes wrong, you do not rush to blame others. You identify what you can do differently the next time and develop a plan to implement these changes.

 3. You understand that vision trumps knowledge

You know that you do not need to have all the answers. As long as you can identify the problem, you can visualise a solution and research the best way to implement that solution.

 4. Personal growth

Meeting the challenges of tomorrow requires learning and development today.  You have a desire to learn and a thirst for knowledge. Learning and development activities form a key part of your schedule.

 5. You seek alternative views

Knowing that the way things are done can always be improved, you willingly seek out the opinions and views of others. You do not feel threatened when people disagree with you. If you feel that their way is better, you are happy to run with it.

 6. Non-judgemental

Variety makes the world a more beautiful place. Even when you disagree with people, you do not feel the need to criticise them. Instead, you respect their right to their beliefs.

 7. Resilience

There will always be things that go wrong. There will always be setbacks and major disappointments. While you may initially be a little upset, emotional maturity allows you to express your feelings, identify the actions you can take, and move on.

 8. A calm demeanour

It’s hard to be calm 100% of the time but you are able to remain calm the majority of the time.

 9. Realistic optimism

You are not deluded. You know that success requires effort and patience. You do, though, have an optimistic disposition whereby you believe you can cope with whatever life throws at you. You also believe that there are opportunities out there for you, so you seek them out.

 10. Approachability

You are usually easy to get along with and people feel comfortable approaching you. Building relationships is never contrived; it comes easy to you.

 11. Self-belief

You appreciate when others praise or compliment you. It feels good when they approve. However, you know that there will always be people who disapprove but you are confident in who you are and what you do. If you believe that a particular course of action is right for you, you will do it, whether they approve or not.

 12. Humour

You don’t take yourself too seriously. You are able to enjoy a good laugh with friends and colleagues, even when you are the butt of the joke.

One of the greatest obstacles to emotional maturity is a lack of self confidence.
