וימדו בעמר ולא העדיף המרבה והממעיט לא החסיר איש לפי אכלו לקטו
For six years while I was in kollel, we ran a small business. There were times when we’re super busy, at other times it was slow. Sometimes we got a great deal. Our customer base constantly fluctuated.
But, we used to total up our earnings every 10 weeks and it always averaged almost the exact same amount (within a few dollars). The only exception was one time when we’re tight for money, we asked Hashem for some extra and we received a bonus.
