Should I fill in Princeton's 'summers' section?

<p>My personal statement covers most of what I would write in this section, and they do say to write it if its not already covered in the common app. But, it is a mandatory field, so I'll have to put something there.
So my question is: Should I write very little since it would be redundant (they clearly say not to be redundant for the main supplemental essay)? Or will not filling it out disadvantage me, and should I try to explore a different perspective of my summers?</p>

<p>Any advice would be much appreciated.</p>
