While Buddha was alive he would find himself being asked the same questions by many different kinds of people. They all asked, “What I can do so that I won’t worry anymore?” Buddha always gave them the same answer, “Just let your worries go then you won’t have them anymore!” 
One day a man, certain he was too wise to believe Buddha’s answer, defiantly asked, “There are hundreds of thousands of individuals in this world. There are hundreds of thousands of kinds of anxiety harbored in their minds. Yet you give an identical answer to everyone. Isn’t that ridiculous?”
Buddha didn’t get angry. He just asked the man, “When you sleep at night do you dream?” 
“Of course!” the man replies.
“Well, do you have same dream every night?” Buddha asked.
The man answered, “Of course not!”
“You have slept hundreds of thousands of times so you have had hundreds of thousands of dreams.” Buddha said to the man with a smile, “But to make the dreams end the procedure is always the same. Wake Up!”
Upon hearing Buddha’s answer, the man had nothing to say for himself.
I like this Zen story. In this story Buddha describes “worry” as being the same as “dream”. As long as we make dreams we can also wake up. As long as we make worries in our mind, we can also let our worries go. No matter what our anxiety is, the remedy is the same.
There is one Chinese phrase that goes like this: “Tian xià ben wú shì,yong rén zì rao zhi” It means, “Nothing troubles Trouble, but a fool troubles Trouble before Trouble troubles him.”
Wise people realized the meaning of life so they don’t troubles trouble till trouble troubles them. They take things as they come but let bygones be bygones. A fool doesn’t realize the meaning of life so he “bends to circumstances, making much ado about nothing.” This world has an endless supply of vexation. Are you going to keep dreaming them up or are you choosing to wake up?
