The following quote has been widely attributed to Charles Dubois, as on the Favorite Quotes blog: "The important thing is this: to be able at any moment to sacrifice what we are for what we could become." However, its correct attribution appears to be to Charles Du Bos (1882-1939), the French critic of French and English literature.
The quote comes from his book Approximations (1922): "...premier tressaillement vital; surtout il s'agit à tout moment de sacrifier ce que nous sommes à ce que nous pouvons devenir."
