Maturity

No one is born perfect. We all are born with flaws.  Everyone begins life with certain character flaws or immaturity. Everyone gets better or worse during life.  Maturity level may get better or worse depending upon your upbringing, your family, your home environment, the books you read, the friends you have and make, the school you go to, all of your experiences, including traumas, illnesses, relationships, work experiences and more can influence how fast you mature or develop your character. These also makes sense why people around the world have different character.

During the process of maturity, it's okay to make mistakes. You can learn something. More mistakes, more fast you get maturity. But it is not good if we make the same mistakes over and over again.

After all, maturity is all about not making the same mistakes, controlling yourself, thinking before making decision, and always have the second thoughts. I mean, you're not being selfish.
