Interpersonal communication consists, by definition, of at least two parties. Do you never find it difficult to understand, to be persuaded, to accept feedback, to take on a proposal, to be encouraged, or motivated by someone? If you're only ever the transmitter of those things then I don't think you're actually communicating; you're just orating. Not to mention that "being friendly", "satisfying interest", and other reasons exist to communicate. Not everything is about your agenda. Maybe internalising that is hardest? (A bit pompous but you take my point, right?)
