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.
Be prepared. Look around first and then come here. Do your homework when you're looking at programs and remember that you stand a real chance of working with OMAFRA and OMAFRA connected researchers here. They really are the best.
Words of wisdom for someone considering grad school...
My advice would be to not be afraid to try anything. Take any opportunities you have for new experiences because you never know what you will end up liking! If I had not tried a wide variety of courses during my time at the University of Guelph, I would not have discovered my interest in reproductive biology. Also, take any opportunity you can to speak with other graduate students; everyone is extremely friendly and always willing to lend a hand if you need it. Your peers are a great resource and are always willing to offer some advice on school, research, or life.
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.
Be patient with yourself. As a student your job is to learn, and by necessity, fail. Solving the problem and having the right answer isn't always the same thing.
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.
