1. Self-awareness
Maturity grows from a seed of awareness; an awareness of the self and the actions you take. Being self-aware means you are able to look at yourself through the eyes of an observer. You can take a somewhat neutral stance to watch your thoughts, actions, and emotions before applying a rational filter to them. Essentially, self-awareness is about building up an understanding of your personality; its strengths and weakness, its potential and limitations, and every little nuance.2. Self-control
Once you have established a robust awareness of yourself, you are better positioned to exert a degree of self-control. You can identify urges that build up within your mind and resist the temptation to act on them. This might, for example, be the difference between getting angry and remaining calm when someone does something you dislike. A mature person is better placed to show restraint towards things that might be detrimental to their short or long term wellbeing. They can triumph over some of the more self-destructive behaviors by recognizing them for what they are.3. Accountability
When you reach a certain level of maturity, you grasp what a great responsibility it is to be human. You accept that we are all accountable for our own choices and the wider impact they may have on the world. The belief that things happen to you is eroded and replaced with a proactive mindset that understands the consequences of your actions. No longer will you live passively among the world; you take strides to change to your situation where necessary so that you can live conscientiously.4. Humility
Even though you appreciate the importance of each decision you take, you remain a humble and modest person. You never take yourself to be above others, regardless of your status, wealth, power, or influence. You know that, when it comes down to it, we are all born equal and we all die equal. You refrain from letting any personal success go to your head and you treat people fairly and respectfully whatever capacity it may be in.5. Self-acceptance
Mature people are able to accept themselves for who they are; they practice kindness even in the face of their shortcomings. You can seek to improve yourself and grow as an individual, but maturity allows you to take your present situation and all the past events that have led to it and make peace with them. It is only when you are able to accept where you are now that you can plan your path for the future.
