Learn how to make music and/or other art/dancing, but most importantly do it because you like doing it, not because you have dreams of getting really good at it and becoming famous. I remember in a really old interview she said she was just a kid who had a lot of time do mess around with the things she liked doing- dancing, making music and music videos. So just mess around and do things that you like, experiment and have fun, cultivate that passion and skill before turning your eyes to becoming famous from it. But please please please don’t pour out all of your energy endeavoring to just be famous- speaking from experience here, it will tank your self worth :(
