Don't be jealous. Be happy for your friends.
(Seven deadly sins/virtues)
Don't be stubborn. Accept that being vulnerable is a strength, not a weakness. Just say "Sorry my bad". There's always time to research and prove yourself later.
(Vallaint's defence mechanisms)
Don't hold each other to high standards. We all make mistakes and deserve chances to improve. Most problems are down to systems, not individuals.
Don't mistake innocent curiosity for being interrogative and argumentative. Other people aren't your own personal Google or Reddit.
Don't use logical fallacies or cognitive biases. Educate yourself on how to make better arguments.
Don't be pessimistic about everything. Give compliments, enjoy the pleasure in the little things, be grateful for what millions don't have.
Don't be selfish like Scrooge.

And the positive version:
Surround yourself with people who bring out the best in you, not bring you down all the time.
Be open and listen.
"Plussing" (not jumping into criticism)
Humility (admit to mistakes)
Nihilistic Optimism (not being cynical all the time, despite existentialism)
Taking a moment to think before responding
Respect (complimenting others - it doesn't hurt)
