Psychologists have found that one of the best ways to make an important decision，such as choosing a university or a business investment，involves the use of a decision worksheet.They compare the actual decisions made by people to theoretical ideal decisions to see how similar they are.Supporters of the worksheet procedure believe that it will help people make optimal，that is，the best decisions.Worksheets require defining the problem in a clear way and then listing all possible solutions to the problem.Next，the related considerations that will be affected by each decision are listed，and the relative importance of each consideration or consequence is determined.Each consideration is assigned a numerical value to reflect its relative importance.A decision is mathematically calculated by adding these values together.The alternative with the highest number of points comes out as the best decision.
   Since most important problems are many-sided，there are several alternatives to choose from，each with unique advantages and disadvantages.One of the benefits of a pencil and paper decision-making procedure is that it permits people to deal with more variables （可變因素） than their minds can generally comprehend and remember. On the average，people can keep about seven ideas in their minds at a time. A worksheet can be especially 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 graduate might seek a position that offers specialized training，pursue an advanced degree，or travel abroad for a year.A decision-making worksheet begins with a clear statement of the problem that will also help to narrow it.It is important to be clear about the distinction between long-range and immediate goals because long-range goals often involve a different decision than short-range ones.Focusing on long-range goals，a graduating student might change the question above to "What will I do after graduation that will lead to successful career？"
