The best thing you can do to increase the amount of money is to let it accumulate interest. The money earns 10% interest per day, so if you spend only what you need to spend on food and medicine, you'll soon have a lot more money available. It takes a little while to build up at first, but soon you'll be earning a lot of interest. For example, once you have a $5000 balance, if you limit your spending to necessities, you'll have at least $5500 the next day, $6050 the day after that, then $6655, then $7320, and so on.
