Living without the ego is freaking AWESOME.
Considering it's the source of pain, unease, discomfort, disconnection, the feeling of being alone and almost all the suffering and misery you can think of, it's great to be free of all that.
I thought you were at least 25 though. You are far more mature and aware than most people your age. Don't worry though, the rules vastly change when you get out of high school, and your values and character has far more impact in the real world. High school is a joke compared to the real world, it really is.
