2 types of people in the world

This is so far what i've classified. Obviously this is not based on real facts or no factual basis.  All based on my experience and personality.. Again whether you fall into category a or b. It doesn't really imply that you have a negative or a positive trait.  Both have its shares of pros and cons.

a. selfish - is somebody who thinks about himself/herself and his/her well being...  he/she wants to be happy. he/she knows what they want. They will do anything to achieve that
b. selfless - people who find happiness with other people. he/.she finds happiness through other people and will give anything that will provide that.  Values other people more than themself thus other people are more important than this person
