In your art find out what the truth is to you and don't switch. Once you switch to something else due to popularity it will be difficult for you to do that as truthfully to the subject. No one really wants to be the Van Gough of their generation, they would rather be talentless and famous like Kim Kardashian; or iterations and degrees of a person like that. But its "The Fountainhead" paradox, to remain in obscurity in your own time doing fantastic work you believe in or to do what is popular to become popular and successful at that. The ones that chisel their own ways and are the unlicked cub for a time being and then turn that into the fathers of something new and successful are the stories that many of us true artists try to achieve. But improbability is most likely our friend.
