I thrive on "I told you so".
Why do you feel the need to be right all the time?
Because it feels great.
It is not good to show how proud you are of being right, people will see it as being arrogant and self-centered. Focus your attention on others and how you can hep them in their lives instead.
I just enjoy thinking that I am right.
You will have a difficult time making friends that way since most people don't like being told "I told you so". You should consider what is best, to be right or to get along with others.
