Unlikable people are difficult to please, irritable, and unapproachable.

Enemies of likability:

SELF-ABSORPTION: Likability is a characteristic that people can develop by being present with others. Your likability increases when you move outside of your own concerns and show others that they have your complete attention.

LACK OF FILTER: Likable people know that not all their thoughts need to be expressed, and they filter their words. People who say whatever comes to mind can be offensive, decreasing their likability.
