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.
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.
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.
I advise prospective grad students to network with as many interesting people as possible. Networking is key to finding research opportunities and gaining experiences. Even simple conversations can stimulate new ideas or help solidify original ones.
“As a U of G student I have taken part in many intramural sports including soccer, softball, football, hockey and volleyball. I have had great experiences, both as an intramural player and captain. The availability of such a wide variety of athletic opportunities for students is a great addition to the university.”
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.
Explore as many different topics and opportunities as you can, talk to lots of different people (who are interested in the same things, and different things!), and don't be afraid to ask for help to find the resources and supports that will help you succeed in what you want to do. When you're choosing an advisor, make sure that they will be able to provide you with the support and mentorship that you want and need, and that you are on the same page about academic and work expectations.
The advice or words of wisdom is simple, do whatever you think you want to do. I mean I had to really figure out if this is what I wanted to do and why. When that was settled, I did my research on programs and such but for me I talked with other academics from different disciplines. I needed to hear what it would be like emotionally and mentally and then think about how I would handle those ups and downs. Once, I had the basics of what I needed, and I knew what I could control, I put my best effort forth and then I felt content with results. This has been my mindset, to understand the coursework, to learn and adapt, and do my best. And once you’re in a program, they want you there, otherwise they wouldn’t have accepted you.
