What does it mean that seasonal and cyclical patterns?

Many personal patterns follow weekly, monthly, or seasonal cycles that become invisible when you only think in linear time.

Example: Every January you sign up for a new productivity system. Every March you abandon it. Every June you feel a surge of creative ambition. Every November you question your career. You've done this for eight years, but because you think in linear time — 'this year will be different' — you never notice the cycle. Plot your journal entries by month. The pattern is not subtle.

Try this: Open your calendar, journal, or email archive. Pick one recurring behavior — energy level, spending, exercise frequency, creative output, conflict with a partner. Chart it by week or month for the last 12 months. Look for peaks, troughs, and phase relationships (does one cycle lead another by 2-3 weeks?). Write down any cycle you find with its approximate period and amplitude.
