The real trick to producing great work isn't to find ways to eliminate the edgy, nervous feeling that you might be swimming out of your depth. Instead, it's to remember that everyone else is feeling it, too. We're all in deep water. Which is fine: it's by far the most exciting place to be.

Through positive thinking and related approaches, we seek the safety and solid ground of certainty, of knowing how the future will turn out, of a time in the future when we'll be ceaselessly happy and never have to fear negative emotions again. But in chasing all that, we close down the very faculties that permit the happiness we crave.

Confronting the worst-case scenario saps it of much of its anxiety-inducing power. Happiness reached via positive thinking can be fleeting and brittle, negative visualization generates a vastly more dependable calm.
