I think it might help to gave a little bit of your background to give context.
The fact that you were self supporting in a city with an internship at what I am assuming was a young age speaks volumes. Adding to that, you mentioned earning scholarships that value extensive community service. I am guessing that you are extremely intelligent, resourceful, talented, driven and hard working.
My point is that as students read your excellent advice that they also recognize that this was an amazing feat.
