If I were you, I'd consider the following advice for each dilemma:

1. I need to buy a new phone. Shall I ask my parents for the money or shall I save up?

   If I were you, I'd think about your financial situation and your parents' willingness to help. Asking your parents might give you a new phone sooner, but saving up teaches you responsibility and the value of money. Consider how long it will take to save up and whether you can wait for it.

2. I want to earn a lot of money when I am older. Shall I get a good education or start my own business after school?

   If I were you, I'd prioritize getting a good education. A solid educational background can provide you with valuable skills and knowledge that will help you in any career, including running your own business. Once you're educated, you can always consider entrepreneurship.

3. I'm Robin Hood. Shall I take money from the rich only or both from the rich and from the poor?

   If I were you, I'd focus on taking money from the rich only. Robin Hood's mission is to help the poor, so it makes sense to target those who have excess wealth. Taking from the poor would contradict your purpose and could harm those who are already struggling.

4. My friend from the UK is coming over for a visit. Shall I advise him to bring a purse or a wallet?

   If I were you, I'd advise your friend to bring a wallet. Wallets are generally more secure and practical for carrying money and cards, especially when traveling. A purse might be bulkier and less convenient for everyday use.

5. I don't know which is better: to pay for my shopping in cash or by credit card.

   If I were you, I'd weigh the pros and cons of each method. Paying in cash can help you manage your budget better, as you can physically see how much you're spending. However, using a credit card can be more convenient and may offer rewards. Just be careful to pay off the balance to avoid debt.

6. I'm travelling to Italy soon and I don't know which currency to take with me: dollars or euros.

   If I were you, I'd take euros. Italy uses the euro as its official currency, so you'll need euros for your expenses while you're there. You can exchange your dollars for euros at a bank or currency exchange before your trip or upon arrival.

7. I'm very rich and I want to start a charity. Shall I help the poor homeless animals?

   If I were you, I'd definitely consider helping poor homeless animals. Starting a charity for animals can make a significant difference in their lives and can also resonate with many people who share your passion. However, you could also explore other causes that matter to you and see if you can support multiple initiatives.
