Experience - that most brutal of teachers. But you learn, my G-d do you learn!!
C.S. Lewis
Life is sometimes quite difficult and challenging. We often fail [or at least I often fail - can't speak for you..:)] and it hurts. One effective coping method is to see all of life as an education. We live - and we learn. A date that flopped is still an opportunity to learn SOMETHING. A remark that led your wife into a fury is also an opportunity for growth. Next time you know what NOT to say. A business deal that went sour might save you from losing a lot more money next time.
So sweetest friends - let's get UP on life. Jews are history's most educated people. We learn from books .... and experience.
Love and Blessings!!!!:)
