Lesson 1, Don't Sweat the Small Stuff
Don’t Sweat the Small Stuff…and it’s all Small Stuff (1997)
Context: Often we allow ourselves to get all worked up about things that, upon closer examination, aren't really that big a deal. We focus on little problems and blow them out of proportion. … Whether we had to wait in line, listen to unfair criticism, or do the lion's share of the work, it pays enormous dividends if we learn not to worry about little things. So many people spend so much of their life energy "sweating the small stuff" that they completely lose touch with the magic and beauty of life.
“Life engenders life. Energy creates energy. It is by spending oneself that one becomes rich.”

Context: Thought is matter as much as the floor, the wall, the telephone, are matter. Energy functioning in a pattern becomes matter. That is all life is … Matter and energy are interrelated. The one cannot exist without the other, and the more harmony there is between the two, the more balance, the more active the brain cells are. Thought has set up this pattern of pleasure, pain, fear, and has been functioning inside it for thousands of years and cannot break the pattern because it has created it.
