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!
Networking is essential when considering graduate studies. I met my research advisor at an informal chemistry meet-up in Brass Taps two years prior to working for him. You'll never know when opportunities present themselves, so it's important to take chances and meet everyone you can.
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.
Smart or slow, doesn't really matter in the end, the point is everyone has their own time zone, all you have to have is your own balance of work, play, and all other stuff, the others don't really matter.
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.
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 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!
Explore as many different topics and opportunities as you can, talk to lots of different people (who are interested in the same things, and different things!), and don't be afraid to ask for help to find the resources and supports that will help you succeed in what you want to do. When you're choosing an advisor, make sure that they will be able to provide you with the support and mentorship that you want and need, and that you are on the same page about academic and work expectations.
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.
