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.
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.
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.
My first piece advice to prospective grad students would be to find a lab or an advisor that you mesh well with and are excited about working with. If you are on the same page and feel comfortable from the start, it makes all the difference. After that, trust yourself and your abilities! You are capable of more than you think.
I would tell any prospective grad students to visit the campuses they are applying to, and talk to students in their program(s) of interest! A major factor in my staying at Guelph was the campus community, and knowing that I would be supported throughout my studies in not only my academics, but also through the social atmosphere on campus.
TAKE initiative. REACH out. LEAD boldly. This program affords you opportunities and connections that you will not receive anywhere else and if you take advantage of these you will become “that” person. “That” person who helped you, “that” person who was proud of you, and “that” person who you wanted to be.
