The thing all writers do best is find ways to avoid writing.
Keep writing. Try to do a little bit every day, even if the result looks like crap. Getting from page four to page five is more important than spending three weeks getting page four perfect.
Writing allows me the time to travel and see the world, which is what I always wanted to do. I'd really like to have been Sir Richard Francis Burton, but it's the wrong century.
Don't try to write to the trend of the moment.
There's certainly more new SF available than when I started writing. That means there's also more bad SF available. Whether there is also more good is a matter for future historians of the field.
I've been writing full-time since 1978.
I write early in the morning, usually after reading portions of at least half a dozen newspapers on the web.
I hear entire symphonies, oratorios, in my head, but I can't write a note.
