How can I create my Workshop Transformation Statement if I can't guarantee something or it doesn’t have any quantitative measurables?

In a situation where you can’t guarantee certain results, you will have to be more general in your Workshop Course promise. But to make your promise more compelling, share success stories from existing clients. Using other people's stories to solidify the promise, even if you have to be a little bit more general with it, is always a good way to back it up. 

Also, what you can guarantee is that you will give them the tools, strategies, and resources to help them get the transformation.
