That's a good advice. Politicians are often very good at making promises, but they can't always deliver on them. If a politician promises to give you exactly what you want, it's important to ask yourself a few questions:

Is this promise realistic?

Is this promise in line with the politician's other policies?

What are the trade-offs of this promise?

What are the chances that this promise will be broken?

It's also important to remember that politicians are not always in control of their own destiny. They have to work with other politicians, and they have to deal with the constraints of the political system. So even if a politician makes a promise that they intend to keep, there's always a chance that it won't happen.

That's why it's important to be wary of politicians who promise to give you exactly what you want. Instead, focus on politicians who have a track record of delivering on their promises, and who have policies that you agree with.

Here are some additional tips for evaluating political promises:

Do your research. Before you vote for a politician, take some time to research their past promises and their track record of delivering on them. You can find this information on the politician's website, or by reading news articles about them.

Ask questions. If you're not sure about a politician's promise, ask them to clarify it. You can do this at a town hall meeting, or by sending them an email or letter.

Be skeptical. Even if a politician's promise sounds good, it's important to be skeptical. Ask yourself if the promise is realistic, and if it's in line with the politician's other policies.

By following these tips, you can make sure that you're not being taken advantage of by politicians who make unrealistic promises.
