He wants to be a writer because it has a social aura to it, it's a sexy career. But that doesn't mean he has the true mindset of a writer. At the end of the day he thinks like an entrepreneur.
He's already does what he should be doing.
On a personal note, I went through this multiple times in my 20s. I desperately wanted to be a graphic designer because I love design and thought being a graphic designer would be a really cool career. But I don't think like a graphic designer, I think like a programmer. I don't have that specific kind of creativity. So while I appreciate graphic design, my true talents are in writing code.
