See, hear, experience
Here is an interesting statistic from a study done in 1946 at The Ohio State University by Edgar Dale. After 2 weeks we only retain 20% of what we hear and 30% of what we see however, we retain 90% of what we experience or do! So encourage any team member who has been to a class to share and demonstrate what they have leared to make them feel good and, to benefit the entire Team and clients.
