I’m a huge believer in this, as it’s my default setting when I head into page writing. If the step outline is in place, you’re not going to lose your bearings. And if you like crossword puzzles, this approach will both feel natural — nailing into place scenes that sing and hence feel “easy” — and uncover new insights into the scenes that come before and after them.
Plus, it helps you neutralize that stultifying dread that comes crashing down when you finally start putting down on paper, imperfectly, what has been perfectly realized in your head for who knows how long. By tackling the scenes that excite you the most early in the process, it helps you break the inertia more quickly, and create page-writing momentum faster. It works!
