Ad agencies do all kinds of market research that ask people what they think they want, and instead, you should be creating things that you want. If you do something and you get it, the rest of the world will get it, too. Trust your own instincts, your own intellect, and your own sense of humor.

This quote is encouraging people to trust themselves and their own ideas. It suggests that instead of trying to understand what people want by asking them or doing market research, it is better to create something that you feel passionate about or that you think is unique. The quote is saying that if you focus on yourself and your own opinions, you will likely develop something that other people will respond positively to.
