I would not tell you where and how...
We are all so creative that we can write anything on any topic whether it interests us or not, whether we know anything on the subject or not.
Pick any word and go from there. Be silly. Be completely ridiculous. The only secret to unleashing your creativity is the ability to relax and let go of judgement.
The only thing to remember - first you create "flow" - let it go in any direction you want and then, only then, you edit and re-write your work. The problem with the "writer's block" is that the judgement comes before the deed, the activity, the writing, the coming up with ideas.
I don't know...
It is not allowed...
You can not create anything being tied up by judgement - regardless whether it is your own or somebody else's.
3) or how ridiculous you think my suggestion is.
Write about how people cannot answer simple questions or how meaningful/meaningless their comments are.
I had the problem writing at the beginning (probably it goes for everyone) and I stumbled upon on the hub "I prefer". It was a very good idea of making a list (it is a poem that does not require rhyming) and from that point you can write your own list and explore each line you come up with writing a separate hub.
My own problem now is time - I have so many hubs waiting to be written and one of the series is "Creativity".
