I felt I grew up when I was about 28. I feel pretty much the same. I get reminded when I look in mirrors that I am not. Hopefully, you keep growing and keep planning things as you go along.
I work alone. Humans are incredible, because when you come alone, they will receive you, they accept you, they protect you, they give you all things that you need, and they teach you all things you must know. When you come with two persons or three persons, you have a group in front of them. They don't discuss with the new persons what is important to them.
