If someone says your too self involved in your conversation, it could mean you might wanna expand your awareness. It could also mean you have shit friends. Who says stuff like that to your 'mates'?

"Barney you talk too much about yourself"
"Well stop being a boring sod and come up with something to talk about then"

You have to check whether the person who said it was being genuine or manipulative. Half of conversation is like that anyway, you talk a load of your own shit, they talk all their bollocks, you make fun of people, chat about interests.
