Writer's Block

Try not starting at the begining. Just write something down regardles of where it will end up.

Don't worry too much about the quality of the language or even the content. You can fix that later.

I write for a living and can confirm that it's very real indeed. I agree with Number24 that it's good to just put down whatever's in your head and make it pretty later and I agree with Barbel that ideally it's best not to try and force it (see what an agreeable chap I am?). However, deadlines often mean that you have to write no matter how difficult that might be at the time. When in the right frame of mind I can bang something out that I am very happy with in a matter of minutes. Other times it will take hours of hard and painful grind to produce even a few paragraphs that I never truly like.

Absynthe also works! 

Yes, that is largely the situation but I think with time I will be able to overcome it.     

This stuff can also come about when a) You're a perfectionist, so you run thru in your mind what it's about, but when it comes to doing 'the big job' well you've already done it haven't you, it can't compete with your ideal draft version.
Way round this? Remember that often as you write new stuff comes to you, so when you get it down chances are all sorts of new goodies will occur to you in transit, so your draft version in your mind is just that.

b) Life has got on top of you. Putting stuff off is a way of exerting control, just as a messy room is your way of telling the world you can do as you please, just as anorexia feels to the victim like taking control of your body in a world where generally you just don't feel in control at all, just as morbid obesity comes from someone having their cake and eating it, really 'owning' their food, it's a feeling of control. Of course, you wind up with a messy room and not the means or wherewithal to sort it, stick thin and dying, or carrying around a few extra stone of weight each day year in year out; what started as a desire to assert control only ends up as an outward manifestation of your lack of it.

c) You have put off the deed it is now in the part of your mind called 'on the backburner' as separate as fact and fiction, past and present. Also, let's face it, if you didn't do it last month, you surely don't need to do it this month and if you didn't get round to it last year, surely the chances are slim you will get around to it this year.

Interesting video, thanks SM.

Most of my writing is composing music, rather than writing prose (I have two albums available on Spotify, iTunes, Amazon, etc, with the third being almost ready) which is comparable if not exactly the same. I do get writer's block regarding lyrics but never have with the music- either a melody comes to mind unbidden or one appears while playing piano or guitar.
Writing lyrics strikes me as Lee discusses in the above video: saying something in a way that hasn't been done before. I find myself dismissing a line if it resembles one I recall from elsewhere, and this leads to block. Sometimes all it takes is a spark of inspiration from a casual remark, but that can't be relied on.

What did Bob Hope do?

I think this is the only way around it and I've started writing a bit again as a result. Getting something down on the page is much better than a blank screen; you can always edit it later to better say what you want it to say.

Yes, professional writers (i.e. not me!) must write every day. And even then, it can be years before they make a breakthrough! Then, when they do, they're called "an overnight success" after they've been writing every day for 10 years!
