A goal: 200 Kč for a game

A goal has an amount, a date and a later pile. A loan is not a goal.

Two hundred have a date, not shouting

A goal is a decision in time. Not “I want a game”. A game for 200 Kč by the 15th of the month from the later pile. If a date is missing, a goal is a poster. If a pile is missing, a goal is a dream that juices will eat.

200 is a practice number. Your number can be 80 or 0. Zero means another goal, or wait. It is not shame. It is a balance.

Jakub shouts “I’m saving for a game”. He spends 30 a day. Tereza puts 20 from each pocket money into the later envelope. After four weeks she has 80. Jakub has 0 and anger at mum. A goal with no envelope is a mood.

Tereza finds out the game costs 200 and the card is a parent’s. Even with 200 she has to come for approval. A goal is not getting around a lock. A goal is having tokens for when a parent says yes or no.

💡

A formula in the head, not in Excel as a mark: how much is missing / how many pocket-money rounds are left. If it does not work, change the date or the goal. Do not change reality with fake income.

An amount, a date, a path

A goal has three pieces. An amount (with Kč). A date. A path (how much of each income goes into later). With no path a date is magic. There is no magic in this course.

A goal may be a mood (a game). It may be usefulness (headphones that last). Tên it. Do not hide a mood behind “I need it for learning” when it is a skin.

When a goal competes with must (a copy, a snack), must wins. The goal moves. That is not a loss. That is an envelope that holds.

A loan of 200 from a friend is not reaching a goal. It is someone else’s goal on your nick. A parent “top up to 200” is not automatic either. You may ask. You must not blackmail with a goal.

Tereza wants to shorten it to “it will be fine somehow”. Jakub asks what the lesson A goal: 200 Kč for a game is for, when a table can do a sum. A sum does not count respect, a PIN, a trap or an envelope. The core is: A goal = an amount + a date + how much goes into later. A loan is not that.

Adults pay the rent. The card, the account and the PIN belong to a parent. A child’s email does not belong here. Pocket-money numbers do not belong on the network. If you break these rules in the lesson “A goal: 200 Kč for a game”, you know a word, not the course.

Pocket money 50 a week. 20 into later. 200 / 20 = 10 weeks. A date after 10 Mondays. Tereza writes it. She will see that “by Friday” is a lie.

Jakub lowers the goal to 100, because 10 weeks is long. A new goal. Honest. It is not riches. It is a calendar.

Practice numbers, not a bank statement. Tereza has 80 Kč in the want envelope. Jakub pushes a step this lesson can name. When Tereza uses the core, either it waits for a parent, or it fits the envelope. If not, anger and a hole are left — proof of pressure, not that the lesson is pointless.

⚠️

A goal with a photo of a game on stories + “send me” is begging and a risk. A goal number does not belong on the network. Not even a pocket-money progress bar.

Why this right now

You are in the course Money with Martin, level Cashier. You can write numbers in a notebook or a table, but the topic is money and decisions, not Excel formulas. The account, the card and the PIN belong to a parent. A child’s email does not belong here. Do not put pocket-money numbers on the network.

This is not the Sheets with Martin course. A table may help, but the mark of success is a decision, not SUM.

You will know this lesson by one sentence: A goal = an amount + a date + how much goes into later. A loan is not that. When you can say it to a parent or a teacher, you have the core. The rest is practice, not magic.

Without a goal the later pile has no name. With a name it lasts. 14 days will show whether the path lives, or died at the machine.

If you skip this, the next lesson in level Cashier will stand on fog. On paper there is 200 (or your number), a date and how much will go into later. It is not a test for marks. It is a safety net, so “A goal: 200 Kč for a game” is not only a heading.

Four things you will build from the course

The course has four small projects. You do not have to do them all at once. Today you add only what this lesson can do.

🪙 Pocket money

A 14-day record: income, spending, balance. What you do not write down is as if you did not spend it — and that is a lie.

14 days: each income — how much went to the goal? A tick is enough.

🚌 Class trip

A budget, a reserve, a plan B. A shared till has rules.

A trip can be a goal instead of a game. One pile, one goal, so they do not fight.

🎮 Game shop

V-bucks and a loot box are a purchase. A subscription keeps going.

A game price can change. Then recalculate the date. Do not close your eyes.

🧾 Stall / mini-company

Cost, price, profit. Three numbers for the class.

A stall: a team goal is another number. It is not your 200 for a skin.

Workshop: one goal on paper

A practice 200 Kč for a game, or your number. No purchase today. No shop email.

  1. Write an amount with Kč, the name of the goal, a date. If you do not know the date, count from the pocket-money rhythm.

  2. How much of the next income will go into later? A number. Not “I’ll see”.

  3. One thing in must that has priority if they fight.

  4. Tell a parent the goal in one sentence. Do not ask for a top-up in the same sentence.

You count when a date and a path exist. A poster of a game with no path number is still a poster. Approval of a purchase is still held by a parent.

Practice: a goal, or a poster?

What is missing? Practice numbers.

  1. “I’m saving for a game.” Three pieces are missing. Which?

  2. 50 a week, 20 to the goal, goal 200. How many weeks? Why does “by Friday” lie?

  3. Why does a loan of 200 not fulfil a goal?

  4. A goal vs. a notebook copy on Friday. Which pile wins?

Now you 💪

Go through three checks. By each one, tick in your head: do I see it, or not?

  1. A goal has an amount, a date and a path.
  2. A loan and pressure on a parent do not wreck a goal — they only fake it.
  3. Must has priority over the mood of a goal.

If something is missing, go back to the steps above. It is not a test for marks. It is a safety net, so you go on with certainty, not with a mess.

Check: On paper there is 200 (or your number), a date and how much will go into later.
