I'm with most of the people that say don't even bother trying. They're not going to get it unless they've been there. I think this especially applies to people that have been to college for things other than nursing. I have a business degree and I can tell you I put in about 1/4th of the time and 1/10th of the effort that I have been putting into nursing school, but most people seem set in the "college is college" mindset.
I work 2 twelve hour midnight shifts each week, am heading into my last two semesters of school, and have a 5 year old boy currently involved in tball, 4-H and riding lessons. I'm very active in my son's school and am currently trying to figure out how to head up the committee for teach appreciation week that just so happens to fall during finals week. There are usually two days a week that due to my work, school, & son's schedule I end up getting 2 hours of sleep or doing 30 hour stretches before I can fall on my face for 5 hours and do it all over. All of that and my husband and a lot of family/friends STILL doesn't truly "get" how difficult nursing school is for me.
*ETA* - Our pass is an 80 and we have 20 of the 52 people we started with.
