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.
My advice for someone who would like to follow in my footsteps is that if you have a passion, have the science mould around your passion as opposed to moulding your passion around the science. For example, my main passion in science is aquatic Species at Risk conservation and ecology, while prior to my thesis I had no interest in molecular biology. It was only when my passion could only be obtained through the lens of molecular biology that DNA became exciting to me!
Also, I recommend one to take every opportunity as it presents itself and to continuously seek out new opportunities. Every relevant job, course, and volunteer work that I have had in my academic career has provided connections and experience for the next opportunity. If you work hard and are passionate about what you do, your day job feels a lot less like work ;)
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.
“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.”
There are so many ways to pursue your passions and interests. I'd recommend that prospective grad students be certain that they are ready for the rigour and commitment required by graduate studies. Be open to new ideas, critiques, and other ways of seeing the world. Learn from your peers, students, university staff, and the wider community, in addition to your professors. Be generous with others and build community. Don't forget where you come from.
I think a Graduate program is filled with opportunities for self-growth and self-improvement in a facet of skills, including research, academics, management, teaching, mentorship, public speaking, and networking. On top of that, it exposes you to a variety of workplaces including academia, research and development, industry, and government.
Most importantly, I believe it's not easy to do a graduate program and many others will agree. There will be many challenges and struggles throughout it but this is a normal part of your program and part of the beauty of science and research! I suggest to keep your mind open and find the opportunity in every situation, because your graduate program will only help you improve yourself both personally and professionally!
