Have a high mind, keep a normal mind and look at the world with a smile. Please help me explain that I hurt his feelings. What does he mean by this sentence?

He wants to encourage himself to focus on something meaningful, aim high and pursue something. He may have experienced some ups and downs in his feelings. Let's face it with a normal heart. He doesn't like things, but laughs at them, and looks down on the world and emotions. For himself, he may not want to make too much effort for this relationship. He wants to let nature take its course. He may be heartbroken after being hurt, but he doesn't want to hate you, so he takes it lightly. If you try to save it, there may still be hope for this relationship, but if you are passive, it is estimated that he has gone too far.
