My son was badly hurt in a fire. After he   36  from a series of treatments, the doctors told him they would not do any operation for six months   37  it took long for the skin to stop shrinking. So, he had to return to college with a visible 10-inch  38 on his face.

I said to my son, “Keaton,   39 will pay any more attention to your scar  40 you do. If it does not bother you, it will not bother  41  .” He took my advice to heart and returned to school with his head  42 high — glad he was alive.

  43  , everyone has scars and shortcomings. Some of you may spend much time thinking that people   44  like you better, if you looked different, or dressed differently, or could have a different and newer  45 .

But you see, like Keaton’s scar, people will only judge you by your looks, or your  46  , or your car, if you are judging yourself by these same false  47 .

One of my friends in college was very  48  . At first, when people met him, they noticed his  49 for about 10 seconds. But this man felt good about himself and spent most of his time  50 about other people’s comfort and welfare.  51 , people ignored his looks. What people  52  was his kindness and his concern for them. He didn’t act in an ugly way so people didn’t  53  him an ugly man.

Therefore, concentrate on   54  you value with yourself, because if you can see that beautiful person, everyone you are in contact with will see the same  55 .
