Do not be afraid to engage with your professors and fellow students. Professors want to help you succeed so do not be afraid to reach out to them. The people who best know what you are going through are you fellow students. Ask how they are doing, ask if they have any tips for the upcoming assignment. Doing this will help make you a part of the LANG community.
Workshops offered through the library and OpenEd are so beneficial to help with your research goals and teaching tips/tricks. Definitely be sure to check these out!
Find what interests you. Many other grad students are much younger than I am and will be entering a life's career following completion of their studies. Looking back, I think it's important to pursue your passion and let the career, money, etc., come from that. During studies, stay on top of things. At the same time, don't neglect other outlets, pursuits, interests: things have a way of connecting in unexpected ways.
Networking is essential when considering graduate studies. I met my research advisor at an informal chemistry meet-up in Brass Taps two years prior to working for him. You'll never know when opportunities present themselves, so it's important to take chances and meet everyone you can.
My best advice for prospective grad students would be to not be afraid to put yourself out there to the individuals you want to work with or those you believe to be the best sources of information. You are your best advocate! I would suggest doing as much research as possible on different graduate programs at various institutions, as well as the research being conducted to find the best fit for yourself. In my experience, asking current grad students how their experience was and how they achieved their goals was extremely helpful as they provided their authentic opinion.
My advice for someone who would like to follow in my footsteps is that if you have a passion, have the science mould around your passion as opposed to moulding your passion around the science. For example, my main passion in science is aquatic Species at Risk conservation and ecology, while prior to my thesis I had no interest in molecular biology. It was only when my passion could only be obtained through the lens of molecular biology that DNA became exciting to me!
Also, I recommend one to take every opportunity as it presents itself and to continuously seek out new opportunities. Every relevant job, course, and volunteer work that I have had in my academic career has provided connections and experience for the next opportunity. If you work hard and are passionate about what you do, your day job feels a lot less like work ;)
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.
Drawing on my experience in academia and research, I would advise prospective graduate students to embrace challenges. When confronted with a difficult situation, tackle it directly rather than trying to avoid it. You'll often find that the solution emerges as you delve into understanding and addressing the challenge at hand.
