It's probably too soon. Over the course of my career, I've encountered a significant number of really juicy stories that I tend not to explain, as there's a lot to lose and not very much to gain.
Traditionally, the purpose of autobiography is to tell all of these stories.
I've got enough potential liability piled up there that I think some of these stories will only come out once I'm good and dead. Not just legal liability -- although I did sign an NDA/non-disparage -- bringing up dirt from past businesses is like mudwrestling with a pig: everyone ends up looking dirty.
In this case, I'm glad to say I acted with complete integrity at every point, but knowing the parties involved, we'd end up in a cesspool of rumors and falsehoods, and no one would come out looking clean.
Live. Learn. Move onto the next business. Give advice in generics. Some people will believe you, and others won't.
