Life doesn’t fundamentally need friends, doesn’t need socializing—especially meaningless socializing only drains you.

The more familiar you are, the more dangerous it is. The more you know someone, and the more you’re in the same circle, once you surpass him it’s easy for jealousy to arise, and you’ll end up getting inexplicable cold arrows.
The people who know you best know how to easily inflict “armor-piercing + critical hit + magic damage” on you.
Don’t have contact, don’t share. If you share your joy in the moment with others, in their eyes it’s just you showing off.
Don’t have deep feelings for anyone. Keep a safe distance at all times, protect yourself. In this life, people are basically adapting to loneliness—live for yourself, and for yourself alone.
