The second sign of selfish is: Teaching

I do not teach. I help.
I want to be a helper, a professional helper, not a teacher. I will work in Uni as a helper.

Kill selfish. The desire to teach is the strong desire of selfish.
I do not have desire for success but a very strong one for teaching because I am selfish.

Only few people have the real desire for success, they just want to look good, famous, feel superior, teach.
