There are such sentence i got from a postcard.

WHY STUDY?

THE MORE I STUDY, THE MORE I KNOW.
THE MORE I KNOW, THE MORE I FORGET.

WHY STUDY?

At first, i felt interested in these sentences. Latter on, i coulud understand that there is no limitation of knowledge. Studying is a process to sharp people's thinking. As long as one small peace of mine idea works to my field, that will be worthy. Besides, acknowledge is not the only and main reason why people study; as for the final goal, i suppose everyone has his/her own answer.
