I have something I call the dinner rule. Simply put; is this someone I would invite to my house for dinner and would I be comfortable with them around my family? If you met someone at a business meeting and they bragged about all of their accomplishments and how they crush their opponents would you be likely to invite them for dinner? On the other hand if the person was amiable, open, at ease and comfortable with their self would you invite them for dinner? I think the answer is self evident.
In an increasingly commercial world that is oversaturated with the hijinks of Hollywood, this is some pretty great insight for those who want to learn a legitimate cultural art.
