In response to the first question I have had, 'What advice would you give a beginner writer?'
In one word - persistence. You have to persist and by persisting, by trying and by venturing, you not only improve your writing and style but also find what works best for you, including the right genre.
Also, do be prepared for rejections. These are inevitable but again, by pitching your work and ideas, you may get valuable feedback, find out more what editors are looking for as well as continually improving your work. And if you follow The Golden Opportunity, as described in Achieve More Acceptances, you could find this opens up some good ways into print.
Good luck, and I look forward to receiving and answering more writing questions in my next posting.
