Depending on what your writing style is and where you see yourself (is this a hobby or do you wish to make a living) will determine where to look. There are endless possibilities out there. With the Internet even more 😉
And lord where to start? First of all, you need to write and write often. If it’s a chore than think twice before considering making this a livelihood. For myself I enjoy it. Since my preteens the written word and developing my imagination has kept me focused on this first love and passion.
If grammar isn’t a strong point then catch up on some basic elementary grammar rules. Boring but think about the payoff.
Once you’ve conquered the basics find out what you’re passionate about. Writing about what you know, what burns inside of you to come out…well, writing it down becomes that much easier. Find an editor, (or a friend whose pretty good at constructive criticism) 🙂 and flush out any weaknesses.
Then start your search first for markets seeking new writers. Sometimes these don’t pay or they don’t pay well however getting your work out there is what counts. Some may work with you under contract, or others may only accept freelancers. Google is your friend and you can type: “column writer wanted” and research the various markets out there. Be confident and assertive in your product it’ll show in your penmanship and will open doors!
If you do not breathe through writing, if you do not cry out in writing, or sing in writing, then don’t write, because our culture has no use for it.
