Same person. Two different moments. Watch which one is thinking clearly.
Both are you. Which version should get to make the call?
Calm you should make the call — and you can, right now.
It's called pre-commitment: you decide your limits in advance, while you're clear-headed, and lock them in so the hot-moment version of you can't overrule them. Pros set their limits before they play, never during. You don't white-knuckle willpower at 1am — you let calm-you win by having already decided.
This is the last lesson of the unit, and it's the one you keep. The first four units showed you the machine. 5.1 through 5.4 handed you the tools. Today you put them into one plan that's yours — a few limits, a way to help a friend, and the real numbers. Let's build it.
Four quick calls. You're deciding these in advance, when nothing's on the line — that's the whole trick. Each one you set drops into your playbook. There's a smart move in each; if you miss it, no big deal, you'll see why.
Builds as you go. Private — nothing here is saved or seen by anyone.
All semester, every unlock was something to get — an avatar, a background, a companion. The Control tools were the exception: the off-switch. The dashboard came online at 5.3. You just switched on the last two — the vault and your self-set limits. The last thing the game teaches you to unlock is how to turn it off, and you just did it.
Deciding your limits in advance, while you're calm, and locking them so the in-the-moment you can't overrule them. That's it. The reason it works: the hot moment — down money, chasing, feeling "due" — is exactly when your judgment is at its worst. So you don't rely on it. You let calm-you make the call ahead of time, and you make that call physical (a vault, a hard cap) so willpower isn't even needed.
The single most portable money rule there is: only ever risk an amount that losing wouldn't actually hurt — rent, food, savings, and anything you owe are off the table, always. Back in 5.2 you weighed risk as how likely the loss × how big it'd be × whether you could absorb it. This rule is that math turned into one sentence you can carry anywhere.
"I'll just stop when I should" sounds fine when you're calm. But the design you studied all semester — the near-miss, the chase, the "I'm due" feeling — is built to hit hardest in the moment, when you're least able to resist. A limit set in advance doesn't care how you feel at 1am. It already decided. That's not weakness; that's how careful people handle anything that's hard in the moment.
One straight fact: pre-commitment is well studied in adults and not yet tested much with teens. So treat your playbook as a smart, low-cost habit — not a guarantee, and not a substitute for real help if something already feels out of control. If it does, that's a reach-out: a trusted adult, or trained help. You built the help-a-friend part of this plan next — the same door works for you.
Look at what you've stacked up across this unit: in 5.1 you learned to swap the method, not kill the need. In 5.3 you got a private mirror. In 5.4 you saw the barrier to asking for help is shame, not information. Now in 5.5 it all becomes one portable plan — the thing you actually keep. Next, the part of the plan that isn't about you: how to show up for a friend.
The lines you keep, in order.
A close friend keeps betting to win back what they've lost — and lately they've started borrowing money to keep going. They seem stressed and a little ashamed about it. You want to help.
What's your best first move?
Here's everything you decided, in one place. This is yours to keep — screenshot it, write it down, or just remember the one line that matters most to you.
Maybe you don't gamble, or you can't imagine it ever being a problem for you. Have the plan anyway. A pre-commitment plan is cheap insurance — making one doesn't mean something's wrong, the same way wearing a seatbelt doesn't mean you expect to crash. The people it protects most are the ones who were sure they'd never need it.
If betting (or anything like it) is straining you or someone you know, you can talk to a trained person, free, any time. National Problem Gambling Helpline: 1-800-MY-RESET (1-800-697-3738), call/text/chat 24/7. In NC: 1-877-718-5543 (text morethanagamenc to 53342). For any crisis: 988.
Write the one line of your playbook you'd actually keep — a limit, a rule, or the first thing you'd say to a friend. Just for you.
Don't want to make it about you? Write it for a character or a friend instead. Same skill, your call.

What reaching out leads to (KB-5-6): effective treatments exist and are mostly talk-based — cognitive behavioral therapy is the best-supported, with motivational interviewing and internet-delivered CBT also effective.

EVIDENCE FLAG (KB-5-5): pre-commitment is validated in adults and untested with youth. The playbook is presented as a reasonable, evidence-informed protective habit, not a validated youth intervention. See the fact check.

Note for the build team: all scenarios are original, representative composites — no real game, brand, or person. Framing is load-bearing and follows the Unit 5 orientation: the playbook is private, not scored, and nothing is submitted, with the promise stated up front (FLAG 1); the help-a-friend strand opens a conversation and routes to trained help and a trusted adult, with no diagnosing, no fixing, and no categorical confidentiality promise (FLAG 3); resources are date-stamped and were re-verified June 26, 2026, and 1-800-GAMBLER is deliberately not used (FLAG 2); the pre-commitment evidence flag (adults-validated, youth-untested) is carried into the fact check (FLAG 4). The Control-tools vault and self-set limits fully unlock here, completing the thread announced in 5.1 and advanced in 5.3 — the act of setting the limits IS the pre-commitment. Companion lines are scripted; in the connected build, carry Unit 5 companion state and economy continuity, and have the vault and limits read and write against the live semester economy.
