Once you pick what you want to do, figure out where you have to start from. Then focus on practicing, if needed by doing it for free. Make sure your audience gets some value and in the return, you will get to do some practice. Sharpen your skills while practicing.
While you are giving it for free, on the other hand, you are converting yourself from an amateur to a professional performer. An amateur might get success occasionally but the science and the art of consistent performance are forte of a professional. And with consistent performance, comes extraordinary success.
Keep working towards building yourself up for that extraordinary success in your life.
