"For me, the desire exists less to get myself a degree than to just go and have the whole college experience, and throw myself into the brain pool and see if I can swim"

This quote by Joshua Jackson speaks with the concept that college is not practically getting a degree, but also about the experience of being in college. He is revealing his desire to immerse himself in the college environment and take advantage of the opportunities it offers. He wishes to take part in the intellectual discussions and disputes that take place in college, and see if he can "swim" in the "brain pool". He is recommending that college is a place to learn and grow, not just to get a degree. He is emphasizing the value of the college experience and the value of being exposed to various ideas and point of views. He is recommending that college is a place to challenge yourself and develop your skills and knowledge.
