African Proverb #9

"Knowledge is like a garden, if it is not cultivated, it can not be harvested."

I believe that the proverb means if you don't refine what you know, you will forget it. For instance if you learn something in preschool and the next year you don't go over it there is a chance you could forget it. Further more if that was the case you would not only forget that you would forget everything you learn each year cause it was not refined. In result i think the proverb is very true.
