Grid your sketch, grid the wall, then go one square at a time. That’s how anything huge gets done.

Huge jobs become possible when they stop being one job. A grid turns an impossible wall into two hundred small, obviously achievable squares, and each square only requires you to copy what is in front of you. Scale is handled by the system rather than by your nerve.

Take whatever feels too big and break it into units you could finish in one sitting. Write the list down and work through it in order without looking at the total. Cross each one off, because the crossing off is what keeps a long job from feeling endless.
