Content creator is a pretty inclusive word. It can mean you are a writer, photographer, painter, film maker, gamer, foodie or a model. There is room for many types of content online. We are heading into an era where people can make money from their passions and they are free to branch out into various areas of interest.
Now it is not easy to be a full time content creator. It does not matter what type of content you choose to create there will be a lot of competition and you will need to put in a lot of hours to stay at the top of the game. And by a lot of hours I mean more than you would a regular 9-5 job. But you don't have to wear pants for most of it so that is the trade off.
However you don't need to be the next viral star to be a content creator. You do not need to quit your job or have years of experience to share your work and make some money. If you are busy with work then post once or twice a week. Take some time off in the weekend of before you go to bed. And you have a phone you can post from so no excuses.
And when I say we are all content creators I mean it. Maybe you are a foodie who likes to try new restaurants. You can take photos of the the special and write a review about it. Or tell us how the last new action movie was. Share photos of your city or write a short story on your spare time.
The point is you do not need to go out of your way to be a content creator, you are already a creative person with an interesting life, just bring that to a site like steemit. It is a good way to make some extra money and you never know the audience you might find.
