Course Philosophy

A good tool is a small promise kept: drink the water before the headache arrives. Step outside while the light is still gold. Breathe for three minutes instead of scrolling for thirty. Know when the last coffee really is. Hang the laundry on the right afternoon. Buy the peaches the week they peak. Nothing here is sold, gated, or watched — every instrument runs in your browser and your numbers never leave your device.

PL 101 — Water

Drink
Before Thirst

Your target is built from your body weight, bumped when El Segundo runs hot. A glass is 8 oz. Tap the glasses as you go — the count resets at midnight and never leaves this device.

PL 102 — Light
Sunrise
Golden hour begins
Sunset
Day length
UV right now
UV max today

Ten minutes of morning light anchors your body clock better than any alarm. UV 3+ means sunscreen; UV 3–5 with bare forearms is also the honest vitamin-D window.

PL 103 — Breath

Three Honest
Minutes

Ready
Box 4·4·4·4 — inhale, hold, exhale, hold

Box breathing (4-4-4-4) steadies you mid-day. 4-7-8 — in for 4, hold 7, out 8 — is the one for falling asleep. Ten rounds is plenty. Nose in, mouth out.

PL 104 — Sleep

Count Back
From the Alarm

Sleep runs in ~90-minute cycles, and waking between cycles beats waking inside one. Set your alarm time; these are the bedtimes that land you on a boundary, with 15 minutes to drift off.

9 hours — 6 cycles
7.5 hours — 5 cycles
6 hours — 4 cycles

Pick the earliest one you can actually keep. Consistency beats duration; the same bedtime seven days running is worth more than one heroic weekend.

PL 105 — Coffee

The Last Cup
Is Earlier
Than You Think

Caffeine's half-life is about five hours: half of that 2 PM cold brew is still working at 7 PM, a quarter at midnight. Enter your latest cup and see what's left in your blood at bedtime.

In your blood at bedtime
Verdict
Today's real cutoff for that drink

Rule of thumb: under 50 mg at lights-out and caffeine isn't what's keeping you up. The cutoff shown is the latest you could drink that same drink and get there.

PL 106 — Line

Is Today a
Drying Day?

Estimated line time

Scored from today's 12–5 PM conditions a mile from the beach: warmth helps, wind helps more, and the marine layer's humidity is the real opponent. A dryer run costs roughly 3–4 kWh; the line costs nothing and is gentler on everything you own.

PL 107 — Season

Eat What
The Month Grows

El Segundo Certified Farmers Market — every Thursday, 3–7 PM, 300 block of Main Street, year-round. Peak of the stalls this month:

In-season produce is picked ripe, travels less, and costs less at its peak. Ask the grower what to buy next week — they always know.

PL 108 — Ocean

The Pacific,
Right Now

Water temperature
Wave height
Wave period
What to wear

Read from the open-water grid off Grand Avenue / El Porto. Longer period means cleaner, more organized swell. Two minutes of cold water does what an hour of scrolling can't — go before you can talk yourself out of it.

PL 109 — Walk

Prescriptions,
On Foot

00:00

Twenty minutes of walking after any meal flattens the glucose spike; twenty minutes at dusk is where the unstuck thoughts live. Leave the headphones at home once a week.
