Next time you are waiting for anything, notice what you are wanting! This will be a source of your tension or impatience. All desire has fear built in - fear of not getting or losing, even before your desire is fulfilled. If you want to be free of fear in life, which is another way of saying if you want to be free of stress, the secret is to want nothing, and then magic happens, for lo and behold, all that you need and more, arrives in your life, at the right time, in the right way. Not what they told us in kindergarten was it?
