What is Holmes Rahe stress scale life events?

Holmes Rahe stress scale life events is a concept in personal epistemology: Your capacity changes with seasons health and life circumstances — plan for it.

Example: You run a freelance design business and every January you crash. Holiday recovery, seasonal depression, short daylight hours, and the financial stress of a slow client month compound into a period where your output drops to 40% of your spring peak. For three years you scheduled ambitious January launches, missed every deadline, and burned client trust. In year four you finally look at the data. You map twelve months of logged hours against output quality and energy ratings. The pattern is obvious: January and February are your trough — capacity at 40-50%. April through June is your peak — capacity at 90-100%. November dips again as end-of-year client demands spike while your energy declines with the daylight. You restructure your year. January becomes maintenance month: administrative catch-up, portfolio updates, professional development, and pre-sold retainer work with flexible deadlines. You schedule your most ambitious projects — new brand identities, website redesigns, speculative pitches — for April and May. November becomes delivery-completion month with no new project starts. The annual output stays the same. The stress, missed deadlines, and client apologies disappear.

This concept is part of Phase 49 (Capacity Planning) in the How to Think curriculum, which builds the epistemic infrastructure for capacity planning.
