The deck
The five suits.
A playing-card deck has suits, and so does CardHabit. Every card belongs to one of five, Physical, Mind, Nutrition, Recovery and Connection, plus the Joker. The suit tells you what kind of day the card asks for. It never changes, and it never locks you out of anything.
Hill Work

Physical
Move your body. A walk, a set, a stretch that costs you something.
The Reading Chair

Mind
Read, write, focus. Fifty pages, one page of honest notes, an hour of deep work.
Cook for Yourself

Nutrition
Eat on purpose. A green plate, a real breakfast, an evening without sugar.
The Long Quiet

Recovery
Rest like it counts. Sleep, silence, a screen-free hour before bed.
One Call

Connection
Reach someone. Call the friend, write the note, say the honest sentence.
The Inversion

Joker
The wild card. Two in the deck, and they ask for something you would not pick.

What each suit asks of you.
Physical
Cards that ask your body for something: a set of push-ups, a walk with no destination, twenty flights of stairs. Scoped small enough to do on a busy day, real enough to feel.
Mind
Reading, writing and focus. Fifty pages of a real book, a paragraph by hand, an hour without switching tabs. The suit for attention.
Nutrition
Eating on purpose rather than by default. Cook one meal yourself, eat a real breakfast, drink water before the first coffee.
Recovery
Rest that counts as work. Phone down an hour before bed, five minutes of silence, a cold shower. The suit most people skip and most need.
Connection
Cards that point at other people: call someone you have been meaning to call, give something away, say the honest sentence out loud. Warm, never performative.
Joker
The wild cards. The base deck holds two true Jokers, and every pack carries one more. A Joker asks for something you would not have picked, like doing the opposite of one default today.
Your strongest suit.
Every card you finish goes into your binder, and the binder counts by suit. Your strongest suit is simply the one you have finished most, for example "Mind, 42 cards". It comes with no perks and no penalties. It is a mirror: the part of your life you actually show up for, measured in cards rather than intentions.
Each card also carries a finish. Most are plain card stock, rarer cards carry a foil edge, and the rarest come in full gold foil. The suit says what kind of card it is; the finish says how rare.
