When an airline asks you to sign a waiver for your guitar just scribble quickly in hard to read handwriting "no thank you" and hand it back. Later if they damage your equipment you can claim you did not understand why they handed that waiver to you.
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!
A graduate student at the University of Guelph is a lot of work, but it is very rewarding. My schedule was even more flexible now than when I was an undergraduate student, which is very important because you have to make time for everything. There are classes and seminars, research, meetings, Teaching Assistantship(s), mentoring, and readings happening constantly. If you plan things well, you can get involved on campus or have a social life, too!
The advice or words of wisdom is simple, do whatever you think you want to do. I mean I had to really figure out if this is what I wanted to do and why. When that was settled, I did my research on programs and such but for me I talked with other academics from different disciplines. I needed to hear what it would be like emotionally and mentally and then think about how I would handle those ups and downs. Once, I had the basics of what I needed, and I knew what I could control, I put my best effort forth and then I felt content with results. This has been my mindset, to understand the coursework, to learn and adapt, and do my best. And once you’re in a program, they want you there, otherwise they wouldn’t have accepted you.
Be informed. Always make sure that you understand each and every step of what you're trying to accomplish, but at the same time don't be afraid to plunge into the unknown. Be mindful of what makes you happy, and pursue your goals with a passion because at the end of the day, when we look back at our accomplishments, the gratification from that is what keeps us going.
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.
Do your research: on the lab, on the faculty, on the department and on the city itself. There are so many different programs/departments and it's imperative you know what you're getting into. Speak to students that are currently in the lab or have recently graduated to get an idea of how things work. There are going to be some tough times in your program and you want to make sure you're surrounded by people that want to support you and help you get through, to be successful.
