(Well, wasn't that an exercise in a vindictive response. I just deleted a novella of a rant about my own brother.)

Long, long ago I learned that I couldn't win and that it was necessary for me to ignore my brother and get on with my own life. My happiness is not dependent on his acceptance of me nor other people's comparisons. If people do choose to do so at your cost then they aren't worth your time and it is no loss to you.
