The “you will learn from our mistakes and disasters…” strategy tells your prospects that you got a bunch of experts together and asked them about the big mistakes they made while trying to reach their goals.
This would work well if it’s an information product.
People are very interested in other people’s failures for two reasons – they don’t want it to happen to them and it will make them feel better and braver knowing they reached their goal, even though they made some mistakes.
NOTE: Failure ISN’T Final. Just because you have tried something and it hasn’t gone according to plan doesn’t mean you should quit. When you make mistakes you learn from them and grow thus making your marketing the much more effective every time.
