Griselda [right side] is a mother of 4 kids, amazing wife and great community leader. She is also the treasurer of a microfinancing enterprise in a small rural community in Costa Rica. On May 16th, 2011, our day started at 9am with coffee and some strawberries I brought for us and ended at around 4pm. She was learning how to use excel as a tool to manage the business's books. She used to spend hours at night working the numbers by hand and as the business grew, the work got even larger.
