Psychologists who study optimization compare the actual decisiols made by people to theoretical ideal decisions to see how sirnilar they are. Proponents of the worksheet procedure believe tirat it will yield optimal, that is, the best decisions. Although there are several variations on the exact format that worksheets can take, they are all similar in their essential aspects. Worksheets require defining the ploblem in a clear and concise way and then listing all possible solutions to the problem. Next, the pertinent considerations that will be affected bv each decision

Since rnost important problems ale multifaceted, there are several altelnatives to choose from, each with \ unique advantages and disadvantages. One of the benefits of a pencil and paper decisior-rnaki'g procedure is that it permits peopie to deal with more variables than their rninds can generally compr.ehend and temember. On the average, people can keep about set)en ideas in their minds at once. A wor.ksheet can be especialiy useful when the decision involves a large number of variables with complex relationships. A realistic example for many college students is the question "What will I do after graduation?"

A decision-naking worksheet begins with a succinct statement of the problem that will also heip to narrow i/. It is irnporlant to be clear about tire distinction between long-range and immediate goals because long-range goals often involve a diffelent decision from short-range ones.

Black tea or green tea iced, spiced, or instant - Africa and South America and throughout Asia. business with major tea producers in Tea is made from the leaves of an evergreen plant, Camellia sinensis, which grows tall and lush in tropical regions. On tea plantation, the plant is kept trimmed to approximately four feet high and as new buds called flush appear, they are plucked off by hand. Even in today's world of modern agricultural machinery, hand harvesting continues to be the prefened method. Ideally, only the top two leaves and a bud sirould be picked. This new glowth produces the highest quality tea. After being harvested, tea leaves are laid out on long drying racks, called withering racks, for 18 to 20 hours. During this process, the tea softens and becomes limp. Next, depending on the type of tea being produced, the leaves may be cnrshed or chopped to release flavor, and then fermented under controlled conditions of heat and hurnidity. For green tea, the whole leaves are often stearred to retain their green color, and the fermentation process is skipped. Ploducing black teas requires fennentation during which the tea leaves begin to dalken. After fermentation, black tea is dried in vats to produce its rich brown or black color. No one knows when or how tea became popular, but legend has it that tea as a beverage was discovered in 27378.C. by Emperor Shen Nung of China when leaves from a Camellia dropped into his drinking water as it was boiling over a file. As the story goes, Emperor Shen Nung dlank tire resulting liquid and proclaimed the drink to be most nourishing and refreshing.
