Make your research project/thesis something you're passionate about. If you have a great idea, take it to a professor and see if you can make it into a project.
“I love Guelph for the downtown area especially the farmer’s market, the pubs, and all of the great outlets for outdoor activities. There’s a strong culture in Guelph that creates a strong community feel to the city.”
Remember that research never goes as planned and to not let failed experiments or unwanted results keep you from working hard on your degree. No one gets through graduate school without failed experiments and huge changes in their project plans.
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.
U of G has a fantastic intramural program. I played ice hockey and dodge ball, but there are many other sports offered. In addition, the University has a new physical education building and every student has access to basketball, gyms, the pool, and hot tub.
To any undergraduate student that wants to pursue graduate school, my best advice would be to study hard, celebrate your academic victories, and don't get caught up on your failures. Everybody has a story of a course they wish they did better in, or a midterm/exam that was an unexpected curveball, but as long as you learn from your past and keep pushing forward, things will work out for the better.
Pursue research that you are passionate about and that inspires you. Graduate studies are a lot of work and can be difficult, and if you're not passionate about your research then you probably won't enjoy it. That being said, don't be afraid to step out of your comfort zone and experience new things, whether that be academically or personally. Also, don't be afraid to get involved, some of my greatest experiences at the University of Guelph have been outside of the classroom.
A right step taken at a right time completely changes your identity. I won't say that your academic journey will be easy, but I am sure it will be worthy.
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.
