I've been writing for the better part of a decade.
Over the years, I have learned that most people who want to become full-time writers or content creators end up failing because they don't have a simple, reliable, and repeatable process for creating.
They think that content is 'art' that must only be done when you feel inspired or that subjecting yourself to a routine and using strategies makes you a sell-out.
Here are some of the other reasons I've learned people fail at the content creation game:
Reason #1: Content creators are hard-headed. They'll ignore advice from people who are already doing what they want to do. Just listen
Reason #2: They take their work too seriously, thinking that the world is waiting for their landmark creation when nobody cares.
Reason #3: They're arrogant and think they're above listening to what the market, and consumers, think about their content.
You don't have to write listicles and make dumbed-down how-to advice to win, but you do have to create a system and work at it every day instead of thinking art is a flash-in-the-pan process.
