Its really dangerous when you start comparing yourself to another person or persons.  Always focus on who you are, rather than who you are not. Draw strength and motivation from your positive and negative aspects and the desire to grow and become a better you.  Things may look good on the outside of another individual, but you never know what they truly have going on.  I've personally beat myself up about where I "should" be in life, but I'm glad I realized a long time ago just how self-destructive that thought process is.  So, I do me.  I enjoy me.  I love me.  Just as I am.
