This is a great lesson. But see more here:

Proverbs 11:24-25 KJV
There is that scattereth, and yet increaseth; and there is that withholdeth more than is meet, but it tendeth to poverty. [25] The liberal soul shall be made fat: and he that watereth shall be watered also himself.

If you extensively maximize the little you are given by God, be of expectant of greater one from Him.
