By coincidence, through the HR.com website I came across some wonderful presentations that were all part of the LEAD Forum. They had some formidable speakers, though judging by the viewership figures on Youtube, not so many people have found these presentations yet.
This is a short highlights video. The full presentations are available through the links on the right of the page, or through the LEAD channel. I would especially recommend the ones by Dr Lance Secretan and Dr Marshall Goldsmith.
