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.
Drawing on my experience in academia and research, I would advise prospective graduate students to embrace challenges. When confronted with a difficult situation, tackle it directly rather than trying to avoid it. You'll often find that the solution emerges as you delve into understanding and addressing the challenge at hand.
While it's true that you should work hard to reach your goal, burnout is real. Allow yourself to take breaks when needed; take a nap, play video games, and laugh at some memes. Life will feel less annoying.
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.
Words of wisdom for someone considering grad school...
My advice would be to not be afraid to try anything. Take any opportunities you have for new experiences because you never know what you will end up liking! If I had not tried a wide variety of courses during my time at the University of Guelph, I would not have discovered my interest in reproductive biology. Also, take any opportunity you can to speak with other graduate students; everyone is extremely friendly and always willing to lend a hand if you need it. Your peers are a great resource and are always willing to offer some advice on school, research, or life.
Try your best to reach out to faculty and make connections with people who share the same passions as you. Everyone at the University of Guelph is happy to share their expertise and provide guidance, and those connections are very valuable in expanding your knowledge and reaching your goals.
Be informed. Always make sure that you understand each and every step of what you're trying to accomplish, but at the same time don't be afraid to plunge into the unknown. Be mindful of what makes you happy, and pursue your goals with a passion because at the end of the day, when we look back at our accomplishments, the gratification from that is what keeps us going.
Guelph is an amazing school academically and socially. You will be able to conduct cutting-edge research, surrounded by people who passionate, intelligent and supportive. There are so many social events and opportunities so don't be nervous to join clubs, teams or come out to social events!
