Perform every task while in your self-respect and others will continue to cooperate with you.
When you are doing something and you are in your self-respect, it creates cooperation. On the other hand, if you have an ego because of which you expect others to recognize your work and appreciate it, it creates competition and jealousy.
Application: When you find someone not cooperating with you, check within yourself why you are performing that task. If there is the slightest feeling of trying to prove yourself, remove it. Let there be the thought in the mind that you want only success in the task and nothing else.
