Be Selfless in the Short Term, Be Selfish in the Long Term

If your typical way of having conversation is the way that i described, you've lost whatever 30 minutes times a hundred 50 conversations are. Instead of listening, letting some else drive the conversation, spend 80 % of the time hoarding knowledge. By being selfless and allowing someone to express themselves in this short term, it will allow you to be selfish long-term.
