If you treat someone sincerely and they let you down, never question yourself; you might be the best person they've ever met in their life. The reason they let you down is that their good fortune is not enough, and their ability to perceive beautiful things is weak. Such beautiful opportunities will not be given to them again. So never change your beautiful nature for someone unworthy. You should remain kind, as greater things are still ahead. Moreover, one must learn to see through others. To see through means to understand; your education level has nothing to do with me, and your annual salary of a million doesn’t affect me at all. I used to think that powerful people were always right and felt I had no right to speak up when offended, as if I had no qualification to refute them. Now I understand that as long as the other person's value is not reflected in my life, it doesn't matter how impressive they are; as long as I do not wish to gain anything from them, we are equal. I don’t need to be more successful than you to have the right to say you are wrong. Remember this: do not envy the rich and do not underestimate anyone.
