What is called a sincere work is one that is endowed with enough strength to give reality to an illusion.
Create something, sell it, make it better, sell it some more and then create something that obsoletes what you used to make.
If everything always went perfectly, I would feel like, When is the ball going to drop? Because good things don't always last. Maybe I'm a pessimistic person. When something just seems too good, I can't believe it.
