I saw a wonderful presentation by a group of summer students on how to conduct a space mission to one of the moons of Saturn. I was struck by the fact that some of these students had very good role models on how to speak to an audience -- and they were from mostly second or third generation "professional" families. Other students lacked confidence and skills.
This is a vital career skill, which will distinguish leaders from other people. I highly recommend the Success Through Communication course to anyone who wants to upgrade their communication skills. This is the training that helped me get my first job at a major aerospace institution.
