There are so many different kinds of writing and so many ways to work that the only rule is this: do what works. Almost everything has been tried and found to succeed for somebody. The methods, even the ideas of successful writers contradict each other in a most heartening way, and the only element I find common to all successful writers is persistence-an overwhelming determination to succeed.
“…Don’t be afraid to be confused. Try to remain permanently confused. Anything is possible. Stay open, forever, so open it hurts, and then open up some more, until the day you die, world without end, amen.” - George Saunders
