My advice would be that a Masters degree is like a roller coaster. You will have your ups and downs in your research but that is all apart of being a scientist! There is no such thing as a 'bad' discovery.
I have always followed my gut and trusted my instincts. I truly believe I wouldn’t have had the opportunities I have had if I didn’t trust that what was meant to happen, would happen at the right time for me. From the short internship that has become a career, to waiting for this program to exist to pursue my masters – timing is everything.
See graduate school as an opportunity to grow in many different ways. UofG has plenty of wonderful research opportunities, and a big part of being a researcher is the chance to communicate your research to different audiences. Graduate school is an awesome opportunity to become a more well rounded person from developing problem solving skills as a researcher to sharpening communication skills, all of which are crucial for any walk of life you end up travelling down.
I would encourage all prospective graduate students to research their program of interest and speak directly to faculty prior to applying as this can ensure that your research goals align with your prospective advisor/program of choice.
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.
Professors at the University of Guelph are exemplary in their professional acumen. Over and above this, there are plenty of opportunities, like Teaching Assistantship (GTA) and Research Assistantship (RA), for an international graduate student to help fund their studies.
Pursue research that you truly believe has the potential to improve life. Knowing you are working toward something more than just a degree can help you find the drive to make it through the difficult or dry aspects of your time in graduate studies.
Your time in graduate studies will provide many opportunities, but don't lose touch with yourself. Take the time to do what you need to in order to maintain your sense of purpose and direction, then live out of that. Don't be afraid to try new things, but remember that no one can do everything. Be selective.
