Should I include the less impressive extracurriculars in my application as well?

Common app allows you to discuss up to 10 activities in your application. I have a six-ish strong activities, as in clubs I’ve been in for four years with leadership roles and activities I’ve won awards for. After that though, there are four other opportunities to talk about activities. I was wondering if it would be a good idea to include extracurriculars like Scioly, which I’ve participated in for only one year or Key Club, another one year extracurricular (freshman year only), or if they would water down my application. If you have experience in judging applications, please give me some advice. And if it makes any difference, I plan on applying to NYU and U of M for business school. Thanks.

You list them with the most important ones on the top. You are who you are. Just fill up the slots even there are some less impressive ones. That would show at least how did you use your time.
