Point 8 refers to the fact that when you stop being an amateur and become a professional, people stop thanking you for what you do because it is supposed to be your duty.
And that is ultimately good, because it becomes that identity that you have been searching for for a long time.
For example,
Imagine that your path is to paint.
First you are not that good, because you are learning but your loved ones encourage you and tell you that you are doing well.
And when you become a professional or are on your way to it, that's when they start criticizing your work. And what is ultimately painful is good, because it means that you are on the way to your dream: to be a professional painter.
