Although I think most prospective grad students have been told about the importance of picking a study/project that interests you, I think it's also really important to take some time to see how you interact with your supervisor and lab. These will be the people you work the closest with for the next several years, and help provide support to you in some of your toughest moments.
I've been very privileged and lucky since coming to Guelph for my undergraduate degree back in 2010 as all of the opportunities I have been given have been gained through building strong relationships with faculty and staff on campus and finding mentors that have helped guide me along my career path. I've always found that the people on campus are incredibly giving and willing to devote their time to help out students. I've also found that simply starting with expressing an interest to be more involved and showing initiative can go a very long way to opening doors to new opportunities.
See graduate school as an opportunity to grow in many different ways. UofG has plenty of wonderful research opportunities, and a big part of being a researcher is the chance to communicate your research to different audiences. Graduate school is an awesome opportunity to become a more well rounded person from developing problem solving skills as a researcher to sharpening communication skills, all of which are crucial for any walk of life you end up travelling down.
Be patient with yourself. As a student your job is to learn, and by necessity, fail. Solving the problem and having the right answer isn't always the same thing.
“I like the fact that you can go out to the Arboretum and walk during lunch. The flowers and the trees provide such a beautiful and serene outlook to the campus. I like how the buildings are not congested into one area but are separated by trees and pathways.”
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.
