Always mystify, torture, mislead, and surprise the audience as much as possible.
Always work with/surround yourself with people who help make you a better version of you. Kindly avoid those who don't.
A writer always writes.
A day of bad writing is always better than a day of no writing.
Regarding the creative: never assume you're the master, only the student. Your audience will determine if you're masterful.
Authors must spend months, years making fantasy believable in a single work while reality runs rampant and complete chaos elsewhere.
