You're collecting cans to save money, but you blow $12 on Gummi-Snakes and Sour Babies at the store. What does this mean?

You will make your dentist sad.
You will ask your parents for $12 extra to make up the difference.
Now you'll never be able to save enough for a bike!
You're a little farther from your goal, but you can still save to make up the difference.

You've spent a portion of the money you were saving, so it will take longer to reach your goal. This serves as a reminder to prioritize your spending goals and avoid impulse purchases that can delay progress towards your financial objectives.
