Looking at one person's work, the result is not very good: you can't get many advantages. Must be like a bee, gather many flowers, in order to produce honey, if bite in one place, the income is very limited, boring.
Knowledge does not necessarily mean culture. Someone has a doctorate, but he doesn't know how to live, how to treat others, and how to treat his children.
一本好書就像是一個最好的朋友。它始終不渝,過去如此,現在仍然如此,將來也永遠不變。
A good book is like a best friend. It remains unchanged, as it was in the past, as it is now and will remain unchanged in the future.
