One of the interesting things about this talk is it gave a number of other people, many of them very high profile, successful entrepreneurs, heroes in the industry, to acknowledge publicly, (and possibly even privately), for the first time, that they can relate very personally to the issues raised.<p>There is a stigma attached to mental health issues that does make it incredibly hard to speak up. People do think that they will be seen as 'weak', 'lazy' or their issues are not important enough to bother anyone else. Anyone in the room that heard that talk recognised that Greg was the opposite - strong, brave and dealing with the issues without losing the essence that makes him, him.
