"When you take something extremely broad, then it is not a work of expansion or work of compression. It's hard because you have to decide what to throw out"

This quote by Iris Chang speaks with the problem of making choices when confronted with a broad subject. It suggests that when presented with a wide variety of information, it can be hard to decide what to consist of and what to exclude. This is due to the fact that it is not a matter of simply broadening or compressing the material, but rather making a conscious choice about what is very important and what is not. This is especially true when handling intricate topics, as it can be challenging to identify which elements are vital and which are not. Ultimately, this quote serves as a reminder that when faced with a broad subject, it is very important to take the time to thoroughly consider what need to be consisted of and what need to be excluded.
