The principle of Creative Limitations calls for freedom within a circle of obstacles and restricted boundaries. Talent is like a muscle: without something to push against, it atrophies. So we deliberately put obstacles in our path - barriers that will inspire us. We disciple ourselves as to what to do, while we're boundless as to how to do it.
Robert McKeeWhen talented people write badly, it's generally for one of two reasons: Either they're blinded by an idea they feel compelled to prove of they're driven by an emotion they must express. When talented people write well, it is generally for this reason: They're moved by a desire to touch the audience.
