What would make a personal development course stand out from the rest for you?

There are a lot of books and courses out there that are available to take. What would you need to see, hear, feel to make you say, "This is different! I know this will help me through my struggles, take me to the next level, receive what I want, improve my relationships, etc."? Is it different than what you need to see, hear, feel to purchase it?

Thanks!
