writing is more inside you than out, but it flows between the spheres, at the line where Life becomes Art. this line is Metaphor. inspiration seems to come from without, even when it does not. the sum of your experience is a rich trove of creation, connected and re-connected through your heart and your mind.
and your audience is the same, ready to assimilate your images into their experience, to recreate them and find resonance.
writing is love and generosity. your love of writing itself, and of the things you choose to write about, given freely to anyone who might share your love.
writing is work, but work you choose to do, work that rewards you with insight and a better life.
the best writing is honest - readers/listeners lose interest with falseness. even when writing fiction, you must tell the truth. which means you must know your story and your characters far beyond what you commit to paper or put to music.
good writing is more grown than built. it grows from an idea, through a conglomeration of related images, ever expanding, freely formed but which will at some point suggest structures with which to organize themselves.
writing needs to be free, uncensored. and unedited, until the final stages. play with the language you love, find rhythm in speech and in the written line, which is only a substitute for speech. language is heard in the head of the reader. trust the sneaky images you find when you play - don't ignore what you think might not "fit". it does - you just have to find out how. put it in your character's hands - what is it to him/her? you can answer this, because you know everything about her/him, or are at least willing to find out.
be brave, have fun, make something new. and be proud.
