Interpersonal barriers are what ultimately keep us from reaching out to each other and opening ourselves up, not just to be heard, but to hear others. Oddly enough, this can be the most difficult area to change. Some people spend their entire lives attempting to overcome a poor self-image or a series of deeply rooted prejudices about their place in the world. They are unable to form genuine connections with people because they have too many false perceptions blocking the way.
Luckily, the cure for this is more communication. By engaging with others, we learn what our actual strengths and weaknesses are. This allows us to put forth our ideas in a clear, straightforward manner.
