I'd say I'm very knowledgable of the resources at my university available to graduate students as well as how to navigate bureaucracy. From health care to fringe benefits and human subjects research to submitting grants, I know a lot. As I've written before, I love connecting people and resources so I love it when people ask.
A fellow grad student asked if I knew of funds to support students to attend a workshop. Indeed, I did. I had already bookmarked the page for my own future use. She was impressed that I could find it so quickly. She said, "This is great! I was sitting in my office thinking, I wonder if Karina knows of any funds. I should go ask her. Thank you! You know so many useful things!"
This makes me feel appreciated. I'm glad to help!
