I get that, the pressure is almost a second‑hand. First thing: map out the whole timeline, then break it into micro‑tasks—one paint, one frame, one light check. If each step is its own small win, the big picture stays manageable. Second, set a “no‑touch” zone: a few hours a day you let the art breathe, you step back, walk away, drink coffee, maybe sketch something random—anything that isn’t the current piece. That pause actually refocuses your mind. And remember, chaos is a creative spark, not a flaw—leave a corner of the wall intentionally wild; it’ll make visitors pause and talk. Lastly, don’t let the deadline become your sole voice. Keep a journal of what feels right, not just what the calendar says. When you look back, you’ll see that the perfect show was made of both precision and spontaneous moments.
