Today is Valentine's Day, and there is no better day to talk about cooperation than today. Any and all relationships require cooperation for success.
The world is primarily constituted on the basis of harmony.
Everything works in cooperation with something else.
Personal relationships are the fertile soil
from which all advancement, all success,
all achievement in real life grows. Put yourself in another's place.
Only then will you know why they think and do certain things.
Once you understand how quickly people will grant your requests
when those requests appeal to their self-interest,
you can have practically anything you go after.
It's through cooperation, not conflict,
that you'll achieve your greatest success.
