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.
My first piece advice to prospective grad students would be to find a lab or an advisor that you mesh well with and are excited about working with. If you are on the same page and feel comfortable from the start, it makes all the difference. After that, trust yourself and your abilities! You are capable of more than you think.
Undergraduate research opportunities come highly recommended as they offer individuals a direct glimpse into the world of research and academia, allowing them to evaluate their own inclinations towards this field. Pursuing a PhD is not a path suited for everyone. A fourth-year project can serve as a litmus test to determine if this path aligns with one's aspirations. If it doesn't, one can easily leave without further commitment. However, if it resonates, exploring the possibility of joining a research group that fosters a strong connection becomes crucial. While enjoying the research itself is important, equally important is finding enjoyment in the people one works with, particularly their principal investigator.
Get involved in the community. Grad school is more than your research project; expand your contributions beyond your field of research and into the community where you are working.
Graduate school is an incredibly enriching experience. Focusing on what interests you most brings a whole new level of richness to your learning. In addition to your courses there are also opportunities to refine presenting skills, attend conferences, and work as a teaching assistant for undergraduate courses which blends education and work experience together to prepare you for a fulfilling career.
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.
