Grad school opens doors! SO many doors were opened up for me just in the last two years of my degree.
Make sure you choose an adviser who is well-known in the industry because they will help you grow quickly in the field. I saw my adviser as a professional mentor and I'm able to go to her with questions about the industry. She has given me so much insight into the future of our professional field which has helped shape my future career goals. Take advantage of all the mentorship opportunities that you can. Grad school is the BEST place for that! Finding mentors when you're not a student is hard. Being a student is a great excuse to find mentors who will be so strategically useful to you, if you take advantage of your time here!
The graduate life experience is great! There are a ton of activities and ways to get involved on campus. The administration, faculty and fellow student truly provide a supportive environment to learn, grow and be challenged.
There are so many ways to pursue your passions and interests. I'd recommend that prospective grad students be certain that they are ready for the rigour and commitment required by graduate studies. Be open to new ideas, critiques, and other ways of seeing the world. Learn from your peers, students, university staff, and the wider community, in addition to your professors. Be generous with others and build community. Don't forget where you come from.
While it's true that you should work hard to reach your goal, burnout is real. Allow yourself to take breaks when needed; take a nap, play video games, and laugh at some memes. Life will feel less annoying.
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.
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!
