You can still listen to others and care about yourself. You can not be a b!tch and still care about yourself. The following is my view of differences.

Caring about yourself is:
- eating well
- exercising and leading a balanced lifestyle
- partaking in activities that you enjoy
- enjoying well-balanced relationships and conversations
- respecting all things, including yourself
- standing up for yourself
- being able to calmly resolve conflict with other people
- making your best interestests known to others
- spending time with people who care about you and love you

Being a narcissist is:
- ignoring what other people want or feel
- talking about yourself without taking the time to listen to others
- putting your own interests above those who are dependent on you (i.e. your children)
- being negative about everyone and everything
- doing things to 'please' others while keeping selfish interests in mind
- talking but not acting
