I think that participation in extracurricular activities for middle school students is almost equivalent to active practice, so I found a few famous quotes about practice and finally realized that I must practice it.

---- Lu You's "Winter Night Reading to Show Ziyu"

A knowledgeable person who does not practice is equivalent to a bee who does not make honey.

——Saadi (Persia)

There are also disadvantages to studying exclusively, so you must get in touch with the real society to make the books you read come alive.

——Lu Xun (middle)

How can a person know himself? Not by thinking, but by doing.

——Goethe (Germany)

It must be practice and practical life experience that taught him such profound theories.

——Shakespeare (English)

Hope it can help you
