Volunteering and trying out different career experiences is essential to knowing what you like/what you are good at. I often volunteer my time to entomological societies or writing blog posts for the public so I can gain more skills in scientific communication. Practicing your skills is what helps build them up.
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.
Absolutely take the time to reach out to current students, alumni, and faculty members affiliated with the grad programs of consideration. Your grad school experience will very much be influenced by the people you are surrounded by during your education and the culture of the program. Hearing from other's experiences and talking to current students is one of the best ways to find the right fit for you.
My academic curiosity propelled me into Bioinformatics research. Upon completing undergraduate studies in Genetics, I was looking for opportunities to build on this foundation. The Bioinformatics program at the University of Guelph seemed to be the right fit.
“Since I immigrated to Canada from Bangladesh in 2001 I have been living in Guelph. I cannot think of a city better than Guelph. People here are very friendly and dedicated to making their city a better place Guelph has a nice blend of rural and urban atmosphere; it's not too big or too small.”
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.
If I could speak to a prospective student, I would tell them that doing your graduate studies at Guelph would be the experience of a lifetime that will always continue with you as you progress through your career. With the excellent facilities on campus, no matter what your discipline, you will come out with not only the academic skills but also the social skills to excel in any workplace.
