I don’t recall the source but I remember someone saying they enjoy hearing people talk about themselves because they know they will always hear something good. I have found the observation to be true.
There is a fine line between talking about self because one needs to and because one wants to. Jesus talked about himself quite a bit. For instance, “You are from below; I am from above. You are of this world; I am not of this world. I told you that you would die in your sins, for unless you believe that I am he you will die in your sins.” – John 8:23-24.
There are four uses of “I” in that statement but few people accuse him of being self-asbsorbed.
In a letter to his father (June 29, 1919) C. S. Lewis referred to self advertisement as a gift, a gift he lacked for which he was thankful,
“My friends tell me that I am at a disadvantage for literary success because I lack the ‘gift of self advertisement.’ My only reply—not expressed aloud—’thank heaven’!”1
It’s ironic how famous someone can become in spite of himself.
“Let another praise you, and not your own mouth; a stranger, and not your own lips.” – Proverbs 27:2.
