I advise prospective grad students to network with as many interesting people as possible. Networking is key to finding research opportunities and gaining experiences. Even simple conversations can stimulate new ideas or help solidify original ones.
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 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.
My advice for prospective grad students is to reach out to people. When I was looking at the CDE program, I reached out to a couple of graduated students in different fields to talk about their experience in the program. This information was very valuable and helped me to make a confident choice. If you have any questions about the program or my experience please feel welcome to reach out.
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.
I heard this quote when I first started my Master's: "Your project at the end is not going to be the same as when you started". Although your overall deliverables/outcomes might stay the same, how it gets done is very likely to shift. Those who are adaptive to change, take proactive measures to complete tasks timely, and are willing to go outside of their comfort zone will be the most resilient.
I have found success in graduate studies by having a solid group of people supporting me. Academia can be daunting and difficult, but having friends and colleagues who are like-minded, engaged, and generally supportive has made my journey possible. Pick your department and supervisor with care, seize opportunities, explore new and old interests, maintain hobbies outside of research, and most of all: stay curious.
I found being in a graduate university environment to be very beneficial for having access to experts on many topics. I would encourage new graduate students to not be afraid to reach out to various professors and other graduate students that can help guide you and offer advice.
