Altruism.
To be selfish is hell. A selfless life is the only life in which you can make gains. Making sacrifices for everyone but yourself. Living and working communally, collective thinking, existing as one. Unite and rule. Help those around you to live a full life. Suffer a little to make someone else happy.

Egotism.
To be selfless is hell. To be true to yourself and only to yourself. To have purely selfish motives and actions. Happiness only comes from individualism, which is achieved through the ego. Stand by what you say, don't compromise, and you can be happy because what you've created is unmolested, untouched by any force outside of that of your own imagination.

i don't necessarily agree with it. But maybe some parts are true.

If someone truly loves you, they will climb mountains to get to you.
