What tense makes you feel the most comfortable, and did you choose it before deciding to write?
I use an omniscient narrator. Before I started to write I never considered what tense to use. It may seem strange, but I was oblivious to the tense I was using, until someone mentioned it. Even then I did not think much about it. I was simply inspired to write. I believe that a natural style is the most comfortable way to write.
Do you mean tense or point of view?
I find that I write more comfortably when I am relaxed... I only choose tension when it fits the plot...
