Intend positive. Stay positive. Be patient with your process, follow the path to success, and set your heart to your goal. Let your service and campus involvement speak volumes of you. Learn, grow, and engage, and know if you want to study, you will always make the time to.

Grad school is a marathon, not a sprint. Take breaks, celebrate small wins, and don't forget to explore the city. Your mental health is just as important as your research.
