I wrote this for screenwriters. im putting a copy of it here.
I'm not a writer of any kind. But I do know when to concentrate on something and when not too regarding creativity.
If you concentrate on something it too long it will cause you'r mind to bog down and even stop in the creative juices of any project you are doing. It's like a light bulb, if you leave that light bulb on tool long it will burn out. The human mind is not suppose to function with it concentrating on something too much. Writers block can happen because of going at something to much. The mind is saying to you that your going at this too much, stop, back off.
The whole key to being creative is to have variety. To never allow your mind to concentrate on something too long or too short.If it's too long then it will burn out, if it's too short you forget key things and minute things which are crucial. You'll wind up losing either way.
The backbone to the key of being creative has to do with a process called "turn on/shut down". This means that no matter what you're working on, you have to walk away from it and get your mind to completely and absolutely forget everything and anything that you've been working on. Not just absolutely forget what you're working on but to forget for a period of time.
The reason why the mind must absolutely and completely forget what you're working on and for a period of time is because the mind is going through a process that you're absolutely unaware of. What it's doing is digesting and analyzing everything that you have done. You can't feel or tell that this is going on because its doing this on the subconscious level.This process that the mind goes through of digesting and analyzing what you have done is actually the back bone of being creative, with out it you can't be creative.
When you eat food, you're body has to be able to digest the food. When you're being creative, which is the equivalent of eating food, your mind has to be able to digest it just like your body has to digest the food that you just ate. you're mind actually does this naturally every time your not thinking of something and aren't thinking of, irrelevant to what it is. Its not just restricted to creativity.
When the mind is digesting what ever its digesting that you have created and don't have your mind on or any thought on, at the same time its analyzing it. When you eat food and you're body is digesting it,its also at the same time analyzing it. What kind of food, are there any poisons that came with the food,how heavy is the food Your body can digest and analyze your food with out you having a thought about it. But with creativity you have to get your mind off of what your creating so that your mind can digest and analyze it.
When your mind is analyzing what your creating, it will do one of three things. It will either 1) find something wrong 2) add creativity to what your doing, such as a "good idea" 3) both number 1 & 2. When you come back to being creative one of those three things will be waiting for you in your mind when you go back to concentrate on being creative. If any of those three things are'nt there then your mind has'nt digested it or has'nt completely digested it.
The amount of time to allow your mind to digest anything your creating is variant. Some times it takes a long time or a short time, some times it does it instantly but this is rare. Its just like when you eat food. If you eat certain kinds of food it will take your system a long time to digest it, with other foods its real quick. It depends on what your eating. The same holds true with being creative, it depends on what your doing. The more complex something is the longer it's going to take for the mind to digest it and Analise it.
The human mind is not a machine where it is suppose to pump out one good thing after another. This is total fantasy and absolutely impossible. There is actually a process the mind must go through in order to be creative. If you violate this process it can create writers block and creativity block.
When creating, irrelevant to whether its screenwriting, painting, or any other form of creativity the human mind must go through this process.
As far as being a screenwriter its actually best to have 3 or 4 screen plays one's creating at one time. Thus causing the screenwriters to go from one screen play to another. This will help prevent the screen writer to get bogged down in any one script. When I work on abstract paintings I do, I always work on 3 or 4 paintings at a time. I never ever concentrate on just one painting. Even masters who are the elite of the painting world have at least 2 paintings at any one time they are working on. you'll never see an artist working on just one thing, it will never happen.
When ever a screenwriter is working on 3 to 4 screen plays not just do they need to get their mind off of what they are doing with anyone script but must also get their mind off of screen writing all together. They must many times totally forget everything about screen writing and everything they are doing in screen writing.
The whole key of creativity revolves around what one is concentrating, how long they are concentrating on anything, how deeply they are concentrating on any one thing and how long the absolutely forget what ever they were doing
good luck (wink)
