Should I list these ECs?

<p>I have a really long list of ECs that I'm considering listing when applying to colleges, but I'm wondering if many of them are worth listing. I know this is a little boring to read, but if you could let me know which of these would be worth listing in apps, that would be great. Also, how would you word these if you were to list them?</p>

<p>Informal English/Writing tutoring (about 20 hours)
Snowboarding - 12 years (didn't take lessons or compete)
Informal Snowboarding instruction (12 hours? I taught 3 friends)
Played Bass Guitar - 5 years (lessons 2 years)
Played Piano - 5 years (lessons 2 years)
Etsy shop selling vintage clothing - summer of 10th (profited about $400)
Helped develop and create DECA section of school app</p>

<p>Are these the types of activities that I should list on apps? Thanks in advance.</p>

<p>The informal snowboarding instruction is questionable. The rest is pretty good it seems like.</p>

<p>Thanks. I’m just worried that these, combined with a long list of other ECs, will make me look uncommitted or like I’m trying too hard? Maybe I’m crazy.</p>

<p>For the tutoring, is that 20hrs per school year? If so, don’t include it.</p>

<p>Try not to include activities that you haven’t really extensively participated in or pursued. Remember, quality and commitment > quantity.</p>

<p>The english/writing tutoring was mostly this year and some last year. Thanks, @capitalamerica‌ I guess I’m just wondering which ones would be considered in depth enough to be included. I don’t want to list things for no reason but I don’t want to leave out information that could make me more interesting.</p>
