text: How can it change someones life? If they are in a bad place right now you can give them good advice by telling them whats good for them and whats bad them. Like if it was a homeless person that lives in the streets and was intoxicated all the time you could help them by giving them good advice so they can move out of that stage of being in the streets. You could help them make better choices in their life and if they made more friends they could get more advice from other people. Another way it can change someones life is by giving them advice for their health or on how to be successful with a business. But advice can make someone really smart it.
