Thats a good question. From what I have been told by people at NJMS, its helpful in these sections to not just put in what you have done, but to put a little personality....a little compassion....or passion into it. Its the same advice I was given about the section on AMCAS where you list volunteering, jobs, etc. They don't say it on the application, but they want you to add in your own feelings in. It makes sense, if I was reading it I'd want to get a sense of who this person is as a person....not just their accomplishments.
Anyways, if it was me writing it, I wouldn't go nuts with sentiment, I'd add in an appropriately placed "being able to do _____ was a great, exciting opportunity I will bla bla bla" here and there. Besides, you have 3000 characters, may as well use them!
Good luck!
