Lemme start by commending this picture you used as your Thumbnail Image. Haha. That's a very awesome picture that shows exactly what the topic is about.

The part about not making decisions when you are angry is very correct and it just feels like a lot of people would make better decisions if they observe this rule. Most of the wrong decisions people have made are decisions they made when they were angry or when they were drunk.

They always regret those decisions.
