This sentence was said by Sir Darlington in the third act of Lady Windermere's Fan written by British Irish playwright and poet Oscar Wilde (1854- 1900), which means: "We are all in slums, but some of us are looking up at the stars."

Darlington originally meant "we are all in the gutter", and the "star" in the latter sentence refers to the woman he loves.

At present, this sentence is used as a chorus in many songs. It is generally believed that it means "we all start from the same foundation, we can be content with the status quo, but some of us strive for success with enough perseverance and courage in pursuit of a dream".

In the corner of a well, my heart is bright.

Oscar Wilde (185410/0/October16-1900101October 30th) on.
