Every mistake has a cost. Small errors may cost you the time it
takes to correct them. Perhaps they'll cause you some
embarrassment. It may cost you a bit of money if you need to pay to
fix or replace an item you inadvertently damaged.
As the scope of a mistake gets bigger, so do the costs and
consequences. For example, if you are involved in a serious car
accident and are found to be partially or totally at fault, it can
cost a lot of money to pay for the injuries and damages caused by
your mistake. That is why we all must have car insurance if we own
a car. Mistakes happen. But we need to take reasonable steps to
make sure that those mistakes don't financially cripple our
families.
