Why this works:
one line, 'build things', sits dead centre the whole time while about 27 cuts fly past in 9 seconds: sketching a content plan in a notebook, lifting in a dark home gym, shooting someone on an old sony camcorder, sorting piles of vintage tees on the shop floor. the text never moves, so your eye stays put and the footage does the proving. the caption 'do > talk' says the same thing without any explaining. good takeaway: pick one short line you live by, hold it still, and let your camera roll be the evidence.
