I agree with the causes, but it doesn't help the kickstart the writing process. I know that fear can be real or imagined. If I was writing a book or some great essay I would be afraid of rejection but I am writing for myself and a few of you who may or may not agree with me, so fear is not the cause of this particular block.
Procrastination is a wonderful excuse for not writing, but I sit down and caress the keyboard, but what comes out is a confusing series of letters and spaces that make no sense.
I have never been a perfectionist, just ask my friends and those who know me. I don't sweat the small details but focus on getting out the big ideas, and sometimes make errors in grammar, and structure that are inexcusable to a perfectionist.
Distractions, yes that must be the reason for the block this time, I have a lot going on at this time of year and it is easier to deal with stuff then sit down and listen to the voices in my head that are trying to escape onto paper or the computer.
