I used to think that “having something to say” meant “knowing some profound truth, and since there is perhaps really no such thing, then there could never be anything to say.” Now I know it can simply mean “something interesting to say.”
it’s all in the word “something” which is open to all kinds of interpretation, depending on how hamstringing you want to be to yourself. ;-)
The important point here, and I know this from experience, is that many writers *enjoy* being hamstrings to themselves. ;) But that still leaves many levels of interpretation! For me, the best writing doesn’t have to start with needing something to say, at least upfront…sometimes. cliched as it seems, the writing can all but write itself!
