Find what interests you. Many other grad students are much younger than I am and will be entering a life's career following completion of their studies. Looking back, I think it's important to pursue your passion and let the career, money, etc., come from that. During studies, stay on top of things. At the same time, don't neglect other outlets, pursuits, interests: things have a way of connecting in unexpected ways.
Life as a graduate student at UofG is always exciting! Every day brings new experiences, learning opportunities, and challenges. One day, I could be conducting lab work, another day I could be attending classes and finishing assignments, while the next day I could be running sensory tests. At the same time, I am surrounded by smart, curious, and enthusiastic students who are all actively looking for ways to improve life.
I would advise a prospective graduate student to do their homework before contacting prospective advisors. Check out their profile on the University website, read their most recent paper, and even reach out to a senior graduate student currently in the lab!
Words about financial support and student well being...
Student Health Services and the Wellness Centre has great, friendly staff who are always willing to quickly help you feel better.
My department gave me a stipend, which has allowed me to spend more time focusing on my work, rather than stressing over the financial aspects of graduate school.
Guelph offers great graduate programs for students that may or may not have research experience. What I have found is that faculty members are very willing to meet with students, and are available to talk about their research and to provide insight about what graduate school encompasses. In addition, getting to meet with current graduate students to talk about what their research is about is definitely an option here at the University of Guelph. I have found that many students are afraid to contact faculty members, but I found it to be very easy and helpful to reach out to the Faculty at Guelph. The University of Guelph definitely has the support system to help students get of glimpse of what graduate school has to offer.
Get involved in the community. Grad school is more than your research project; expand your contributions beyond your field of research and into the community where you are working.
