<b>Ch. 18: The Seasonal Spike That Lied to Me</b>

Q4 2024 the reef site had a glorious November — Black Friday, everyone upgrading tanks, revenue spiked to $720. I extrapolated like an idiot: '$720 x 12 = $8,640/yr, I'm crushing it.'

January it did $380. February $360. The November number wasn't my baseline — it was a seasonal bubble. Aquarium spending peaks in Q4 (gifts, holiday setups) and craters in mid-winter and summer.

I'd nearly made two bad decisions on the strength of one fat month: I almost hired a fourth writer at November's run-rate, and I almost listed the site at a multiple based on the spike. Both would've been built on a number that existed for 30 days a year.

The fix was discipline: I started managing the site exclusively on trailing-12-month averages, never a single month. My TRUE monthly average for that year was $441, not $720.

Lesson banked: never plan, hire, or sell on your best month. Seasonal niches breathe — every high month has a low month hiding two quarters away. Underwrite the whole business on the trailing-12 average, and treat the spikes as bonuses, not baselines.
