One key piece of advise I give artist is to recognize this is a business. It takes more than just talent to make it in the Music Business. If you need to invest in yourself to do public speaking then do it. Have someone on your team to help you be able to articulate and separate yourself from others. Just because you rap or trap doesn't mean you have to sound as if you're uneducated.
Build your fan base have the labels searching for you if that's what you desire. But, again, realize this is the music business, excutives and corporations are always thinking about the bottom line.
