Yanivo, I didn't mean to upset you - all evidence of my left field sense of humour!
Lots of people find it hard to get started, and so the only thing to do is just grit your teeth and get started no matter how you feel. I find often once I get started, I quite enjoy getting the thing written (not always!). Even if you have to discard most or all if what you write, at least you've gotten started.
