<p>@jshain, hold it there for a moment, I never said there was anything wrong with doing a number of things with differing focus, I merely pointed out that his lack of a strong focus for his interests both makes it harder to correlate his academic interests with his ECs and it might be seen by admissions officers as having a lack of passion/goals (thus perhaps a need for clarification in his essays). Pointing out a possibility, never meant to cause a controversy for you.</p>
