Dustin - if you want to find the beauty within a person then your first step is to open your mind to that person. That means allowing their attitudes, likes and dislikes to have priority over yours. It means being interested in their life, understanding their aspirations, and accepting their opinions. Only once you've opened your mind will they show you who they are. Then you may be able to discover their beauty within.
The alternative is to project your attitudes, your opinions, and your aspirations onto them. A good model will allow you to do this; a very good model will actively help you. But don't for one minute think that you're showing their beauty within. You're actually doing the opposite. You're using them as a canvas, a prop, an object; you're showing what's within you not what's within them.
