Wouldn't it be wonderful if you could have all your wishes fulfilled? We assume that if a person's big wishes come true, then happiness will be a cinch. Not necessarily so. Even if a wish is fulfilled, it could be disappointing. I remember hearing a story about an entire city where everyone was blessed that one wish of theirs would be fulfilled. Most of the people wished to win the large city's lottery. And they all chose the winning number. Since the grand prize was going to be divided among all those who made the correct choice, they had to divide the large amount of money between a large amount of people. The actual amount won was therefore only a few dollars each.
A great Chasidic master once gave this formula for having your wishes met. "If things don't go the way you wish, wish them to go the way they are," advised Rabbi Mordechai of Lechivitz.
Spiritually, what is best for you is what is. Therefore if you were able to see all of reality, you would really wish for exactly what is best for you, which is your actual experiences.
(From Rabbi Pliskin's book "Happiness, p.127)
