Egotistical

2.  Egotistical- An egotistical person is obsessed with himself, they think that they are the only important person. If they ever consider another person, they would be thinking about someone else being lesser than them.  An egotistical person is extremely conceited, boastful and narcissistic. 
# The story of Narcissus is an example of a person so egotistical that they drowned by staring at their own reflection in a lake for so long. 
# "I am God's vessel. But my greatest pain in life is that I will never be able to see myself preform live." -Kanye West
