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.
Be prepared. Look around first and then come here. Do your homework when you're looking at programs and remember that you stand a real chance of working with OMAFRA and OMAFRA connected researchers here. They really are the best.
Grad school opens doors! SO many doors were opened up for me just in the last two years of my degree.
Make sure you choose an adviser who is well-known in the industry because they will help you grow quickly in the field. I saw my adviser as a professional mentor and I'm able to go to her with questions about the industry. She has given me so much insight into the future of our professional field which has helped shape my future career goals. Take advantage of all the mentorship opportunities that you can. Grad school is the BEST place for that! Finding mentors when you're not a student is hard. Being a student is a great excuse to find mentors who will be so strategically useful to you, if you take advantage of your time here!
Volunteering and trying out different career experiences is essential to knowing what you like/what you are good at. I often volunteer my time to entomological societies or writing blog posts for the public so I can gain more skills in scientific communication. Practicing your skills is what helps build them up.
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!
Coming from New York City, Guelph was definitely different but I would say it was a relief. It truly grounded me to not be amongst the hustle and bustle every day and it's a small town full of nice people.
I loved being a PhD student here. My advisors and labmates were all very supportive of my research endeavors. I enjoyed being in charge of my own research project.
