It is easy enough to be friendly to one's friends. But to befriend the one who regards himself as your enemy is the quintessence of true religion. The other is mere business.
There's a great quote from Henry Kissinger, which I became aware of from reading [Joseph] Heller's Good As Gold. He said: 'Every great achievement was a dream before it became a reality.'
A true friend knows your weaknesses but shows you your strenghs; feels your fears but fortifies your faith; sees your anxieties but frees your spirit; recognizes your disabilities but emphasizes your possibilities.
