Too broad interests and too much leadership... is it bad?

I seriously wonder if having too borad interest(this and that) and/or being a president/captain in several club/activities would be negative.

do colleges want to see a few deep concentrated interests?

<p>I don't know if there's such a thing as 'too much leadership!' lol, seriously most Ivies & competitive LACs want leaders.
As for broad interests, i have that problem too. I guess it depends on whether schools want well-rounded students, or students who excel/are passionate about one or two things.
I think it's def. better to, for example, have won a national piano competition w/ no other ECs, than to be a member of every sport & club in your school. But, a piano competition winner w/ other ECs is def. better than one without. I guess it's all about balance. :)
As for your app, consider listing all your involvement, then highlighting 2 or 3 things as your most significant/accomplished.</p>
