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.
