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.
This is a program that is very responsive to student needs, so if you have a question or want to pursue a line of discussion, be sure to ask! There is a considerable commitment to participants' career and personal growth, as well as to the more formal education elements. I appreciated that "all-around" approach.
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.
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.
The faculty profiles page, on the Food Science Department website, is very useful to help find research projects that you may be interested in. Do not hesitate to email or talk directly to the faculty members. They are always welcoming, and can even help you apply for scholarship funding!
Always ask for help. When in doubt, ask; When not in doubt, ask. Enrolment in graduate courses can be very small, and grad life can sometimes feel isolating; so, try to form great bonds with other grad students. You have a lot in common! Try to take some time off to have fun, and when you inevitably encounter students pulling a tractor in September, do the opposite of what I did; and be cool! If you can, participate in the 3-minute thesis competition (3MT); it's a lot of fun!
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.
