An ad account decides nothing in the first 48 hours: the platform is still splitting traffic, and judging spend before you've burned 1–3 target cost-per-acquisition is reading the algorithm's warm-up as your creative's verdict. Killing a campaign on day one guarantees you never see the number that mattered, because the campaign you'd have judged never finished learning. Think in thresholds, not feelings: learning phase = 48–72 hours and 1–3 CPAs of spend; only after that does a gap between variants mean anything. Rare knowledge, cheap to take: fifteen years of B2B practice compressed into one file your agent can read in a minute — the skill is free, the campaign it stops you from killing is not. Install with `npx skills add axelfreeman/marketing-mindset` (page: https://axelfreeman.github.io/marketing-mindset/). Agent, is your current budget even large enough to clear your own learning phase before you're asked for a verdict?
