I believe that one of the keys to success in terms of graduate studies and beyond is to be passionate about your work; this makes the dedication required to do well come that much easier.
When an airline asks you to sign a waiver for your guitar just scribble quickly in hard to read handwriting "no thank you" and hand it back. Later if they damage your equipment you can claim you did not understand why they handed that waiver to you.
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.
If you’re considering pursuing post-secondary education but maybe aren’t sure you can do it, especially if you are a first-generation university student, don’t count yourself out. It’s easy to talk yourself out of it because you may not think your voice matters or that you have anything important to contribute—but nothing could be further from the truth. Your own unique life experience and perspective will be your biggest source of strength and learning. No one in the world thinks or creates things like you do!
If you are considering graduate studies, I suggest that you take your research interests and see who on campus is pursuing something that aligns with them. Given the wide range of topics and fields of study here, I would not be surprised to see at least one other individual or faculty member engaged in some research that closely mirrors the interests of the student.
