It is amazing how much both happiness and efficiency can be increased by the cultivation of an orderly mind, which thinks about a matter adequately at the right time rather than inadequately at all times.
At the quantum level our universe can be seen as an indeterminate place, predictable in a statistical way only when you employ large enough numbers. Between that universe and a relatively predictable one where the passage of a single planet can be timed to a picosecond, other forces come into play. For the in-between universe where we find our daily lives, that which you believe is a dominant force. Your beliefs order the unfolding of daily events. If enough of us believe, a new thing can be made to exist. Belief structure creates a filter through which chaos is sifted into order.
Let us again pretend that life is a solid substance, shaped like a globe, which we turn about in our fingers. Let us pretend that we can make out a plain and logical story, so that when one matter is despatched — love for instance — we go on, in an orderly manner, to the next.
