For a lot of writers, getting an agent is a major goal. A high profile agent connects you to a high profile publisher, who connects you to a high profile, six-figure book deal, so you can write your high profile, best-selling book.
Here's the problem with that though, the six-figure deal can only come from the publisher. And the publisher won't talk to you until you have an agent, and an agent won't be interested until you've written a book.
So many people believe the lie that they need to be "discovered" so they can create. But it's actually the other way around. We have to create first if we ever want to be discovered.
You're not given the platform so you can make things. You make things in order to build the platform.
