Output is the quality and quantity of the work you produce. Outcome is the reaction to the work you produce. You have full control over your output. You have no control over the outcome. Creatives get themselves in trouble when they try to control the outcome, feel they are owed a "positive" outcome or allow a "negative" outcome to fuck-up their creative process. The only remedy to relinquish control of the outcome, is to take full control of your output. Create as much work as you possibly can, as fast as you possibly can.
