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.
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.
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.
Coming from New York City, Guelph was definitely different but I would say it was a relief. It truly grounded me to not be amongst the hustle and bustle every day and it's a small town full of nice people.
My advisor was more like my mentor. He is very open, honest and helpful, which made me very comfortable to express my ideas and also to discuss different issues concerning my academic life.
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.
Guelph was actually one of my top choices for my undergraduate degree. Having chosen a different university to do my undergrad, when applying for graduate school, I knew I wanted to attend Guelph to continue my studies! The CJPP program appealed to my criminology background and my work experience in the criminal justice system.. I knew this was the program for me!
Words of advice for someone considering graduate school.
Do not hesitate to ask questions in all aspects of overseas study. Your peers, professors, graduate coordinators, and everyone you meet here would love to help.
