Every so often, the thing you’re doing loses steam. Sometimes you can work through it: just keep going and hope it’ll turn out okay by the end. It usually does.
But not always. For those times when inspiration is tumbling out of the mouths of friends and colleagues alike, I like to keep tabs on the next thing I’d like to do, future projects, and continually feed that cycle with new work.
It sounds like an oversimplification, I know. But I feel like this simplistic method is pretty solidly apt. Keep a space at the back of your mind as a workshop for poking around with the next project(s), and always have an incoming feed of other works by people you admire.
