Most economists rely on computer printouts of numerical data for their financial planning.
By comparing one series of digits with another they can find the immediate trends in the economy and take advantage of those trends. To most people that seems normal. To me it always was, and still is, artificial. I have always wanted to help both people and the environment, and I learned at an early age that knowledge of the economy could be one tool to reach that end. However, I wanted more than just the knowledge of how to generate a positive series of numbers.
