You are locked in a basement with nothing but your tools of trade. Forget about bathroom, hunger and all other distractions that may come your way. You spend there enough time to produce the best product you are capable of creating. It may take a week, a month or a year. Doesn’t matter. What matters is that it is as perfect as perfect gets.
You get out of the basement and pat yourself on the back for a job well done. “Maybe I should sell this to others”, you think. WRONG.
