Being vengeful is sometimes necessary. It's not a virtue, but it's not a vice either. If the market for justice is inelastic or rigged, make your own. The hard part is to not go overboard - being fair to someone who hurt you, once you have them beaten, requires great self-discipline.

And yes, if someone just sort of declares themselves CEO in interviews just because they have a famous relative and have an easier time getting invited to talks, me insisting that we are equal partner is humble. This person contributed little else to the business.

I don't have a problem with marijuana (don't want any, but it should be legal), I have a problem with people who steal credit for my work.
