When you only have a few dollars, you’re very careful about how you spend them.
Likewise, if you knew you only had a few days left in this life, you’d be very careful about how you spent them.
But even if we have many dollars, we can still spend each of them carefully.
And even if we think we have many days, we can still spend each of those days carefully, too.
Thing is, you can always make more dollars when you run low. You can’t do that with your remaining days.
