From Science Creative Quaterly:

Finally, in many ways you will turn into your advisor. Advisors teach very little, but instead provide a role model. Consciously and unconsciously, you will imitate your advisor. You may find this hard to believe now, but fifteen years from now, when you find yourself lining up the tools in your lab cabinets just like your advisor did, you’ll see. My student Alison once said that choosing an advisor is like choosing a spouse after one date. Find out all you can on this date.
