Are there formulas on dealing with the type of people out there, if there are 5 types of personality?

I wish!: A "type" is a general classification based on several characteristics. But it's not a hard & fast classification. We are complex creatures! Everybody acts & reacts differently. It is always safest to follow the Golden Rule: treat others as you wish to be treated. That is: be kind, be respectful, pay attention & listen. Look people in the eyes when you talk, don't be mean, & say please & thank you!
