Your best writing is always about the things you hold dear. Oh, sure, you can rant and hate on something and get a good funny article or poem but it all runs out after a while- and often the haters are using the tool they hold dear- words and rhymes- as the 'subject'- but in the end cleverness devours itself and leaves that monotonous dulled feeling behind. Whereas resonant images are the gift that keeps giving. When you hold something dear you can return again and again for inspiration and material. Get used to thinking and identifying 'stuff you love'. Become like a foodie with their somewhat over the top interest in flavours and ingredients- search out the good stuff. And much of it will be in your past- places you have seen and people met and things experienced. Or it could be a story or image from a book or movie that has simply grown over the years incubating in your noddle waiting to be used. Cultivate these images, work on them, play with them: they are the essential building blocks of the dream that becomes your book, story, novel, film.
