First, third, or another person? What writes best?
I always wrote my first stories in the first person. I wrote as ‘I’. I had good reasons for that. I had just started, the writing was still a bit difficult, and I actually started with stories about myself, which simply wrote best in the ‘I’ form. In a later stage, I sometimes converted my story to the third person.
Many writers tend to stick to paths they once chose. You can be successful in this. However, I recommend that you experiment as a writer. Throughout your writing life. No matter at which level, it will give you a lot of satisfaction as a writer.
Stuck with writing? The shoebox!
Write! Little bits, whenever it suits you. During your lunch break, on the train, while waiting for a meeting that just won't start, a pointless meeting that just won't end, or a soap opera that won't get exciting. Try it, fifteen minutes before going to bed. Or when you can't sleep.
