Ideally, you would aim to have roughly 5 units of money, because at that point, you’ll have the least amount problems possible. If you have more ore less, there will be more problems. Interestingly, if you have negative money (i.e. debt) you can have lots of problems, but so do those who have a lot of money. Also, the amount of problems you have increases quite rapidly as you deviate away from the sweet spot.
