I am currently in search of a speaker for my grandfather's birthday event and thought I'll check it here on the forum, cause this forum always helps me urgently. Well, I found this topic only, no more information, unfortunately. However, one of my friends shared a motivational speakers article, where you can actually choose yours and get in touch with them. And I thought, why not share it with you guys, for those who maybe like me searched here on bitcointalk forum.
