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 would advise a prospective graduate student to do their homework before contacting prospective advisors. Check out their profile on the University website, read their most recent paper, and even reach out to a senior graduate student currently in the lab!
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.
Although I think most prospective grad students have been told about the importance of picking a study/project that interests you, I think it's also really important to take some time to see how you interact with your supervisor and lab. These will be the people you work the closest with for the next several years, and help provide support to you in some of your toughest moments.
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.
If any student wants to get research experience, he/she should get into this graduate school. The University of Guelph has unique and fully equipped laboratory facilities. Any grad student can take a long step on their desired research path. Meanwhile, coursework will also help students for learning the different disciplines.
To future graduate students, it is important to keep a clean, legible, and logical lab notebook! Also remember that your brain is your best weapon to succeed in graduate school and it functions best when it is well-rested; only pull all-nighters if necessary. Learn to manage your time and try not to do multiple things at once; multi-tasking in the lab can lead to errors in experiments. Finally, enjoy your time and get all the food and freebies from conferences and other events!
