Finding your passion will take you to the right place at the end of the road. Just keep doing your best and appreciate all the opportunities provided along the way.
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.
If you come to Guelph, your program will be full of like-minded students who have the same passion that you do for your research. The environment you will be in is the most supportive environment you can have for when you are pursuing something that you love.
I believe that one of the keys to success in terms of graduate studies and beyond is to be passionate about your work; this makes the dedication required to do well come that much easier.
Think hard and explore the options of different pathways you can take in graduate studies. Make the best out of grad school, be social and go to events to meet others in your program. Enjoy your time here, it goes by extremely fast.
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.
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.
Identify your passion and reason(s) for wanting to become a graduate student. Write them down, type it up, post it large and visibly on your desk or wherever you do your work so that it remains a constant reminder of why you are doing what you are doing and will motivate you through the hard times that every graduate student has and does go through, so that you can always see the light at the end of the tunnel.
