Sharpen my understanding whilst I spread my knowledge
Albert Einstein said that If I give you a pfennig, you will be one pfennig richer and I’ll be one pfennig poorer. But if I give you an idea, you will have a new idea, but I shall still have it, too.
For me, don’t care what we give to another people, we will definitely get the return. And it is usually bigger than we give.
nb: For you to know, A pfennig is smallest unit of German currency (100 pfennings make a mark), but now they use Euro as national currency.
