<p>Get a life sschoe. Do you have nothing better to do than post on this forum and harass science majors almost every day? The OP is obviously smart enough to be very successful at anything he chooses to do, that includes getting a PhD and becoming a professor. The people who should not go for a PhD are the ones who barely scraped through undergrad with a 3.0. They are the ones that will be stuck in post docs for years because positions in academia and industry will be given to those who are truly gifted in their subject. Science is highly competitive and only the best, brightest, and most passionate will be successful, which the OP obviously is.</p>
