You don't believe that your friend could ever do anything great. You despise yourself in secret, even – no, especially – when you stand on your dignity; and since you despise yourself, you are unable to respect your friend. You can't bring yourself to believe that anyone you have sat at table with, or shared a house with, is capable of great achievement. That is why all great men have been solitary. It is hard to think in your company, little man. One can only think 'about' you, or 'for your benefit', not 'with' you, for you stifle all big, generous ideas.
Each one of us is the architect of his own fate; and he is unfortunate indeed who will try to build himself without the inspiration of God, without realizing that he grows from within, not from without.
Live life so well that, even if you die, the empty seats behind you will tell the story that, "yea, this soul did what God sent him/her to do". Give life and hope into your family, village, community, country, continent and the world at large. You can do it!
