Hello. My name is iB, and I am an insecure writer. Knowing this does not help. It compounds the problem. I second guess everything I write/type and as a result, find that I spend more time backspacing than I do pushing forward. When you couple that with writers block and a healthy dose of O.C.D., you get unfinished projects that linger in the brainials just long enough to be forgotten and I hate that because many o' great ideas have fallen to the wayside due to said hesitation.
Along with the aforementioned hesitation, fear is another (and probably the most destructive) reason as to why I cannot finish anything that I start. It's the fear of failure. The fear that, among real writers, my idea not be received well and in turn, ripped to pieces because it did indeed, suck, and if that were the case, it would be the death nail in the box that seals the fate of any future attempts of writing anything with substance.
If you wish to take part in the Insecure Writer's Support Group, mosey on over to Alex J. Cavanaugh and inquire within.
