I found being in a graduate university environment to be very beneficial for having access to experts on many topics. I would encourage new graduate students to not be afraid to reach out to various professors and other graduate students that can help guide you and offer advice.
Sometimes as an undergrad it's easy to stay 'behind the scenes' and just go to classes and complete what's required of you. But grad school has SO much to offer, and there are opportunities to gain new experiences around every corner that contribute to both personal growth and look great on a CV. I think getting involved is so important, and creating new relationships with faculty/other students is key.
Make sure your decisions are based on a meaningful purpose. The phrase “What you put in is what you get out” is what I return to repeatedly. It applies to you as a person, the work you do, and the food you make. You need purpose to make anything of consequence happen. It’s been over a decade since I made my first decisions to enter the field of food safety, and I’m even more committed to it today than I was then.
A right step taken at a right time completely changes your identity. I won't say that your academic journey will be easy, but I am sure it will be worthy.
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 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.
Pursue research that you are passionate about and that inspires you. Graduate studies are a lot of work and can be difficult, and if you're not passionate about your research then you probably won't enjoy it. That being said, don't be afraid to step out of your comfort zone and experience new things, whether that be academically or personally. Also, don't be afraid to get involved, some of my greatest experiences at the University of Guelph have been outside of the classroom.
