The most valuable sentence in marketing is one agencies rarely say: stop spending that. Businesses accumulate marketing the way houses accumulate furniture — a channel here, a subscription there, a campaign someone launched two years ago and nobody switched off. The first job of good consulting is subtraction.
The second is measurement designed like an instrument panel: a handful of numbers that connect marketing to money, agreed definitions, one source of truth — so decisions stop being arguments between opinions and start being readings of the same dial.
The third is focus. Growth is always gated by one constraint at a time — not ten. Find it, fix only that, then find the next. Businesses that fix their constraint monthly outrun businesses that do everything at once, every time.
