Your goal is to be as efficient as possible so you can get your work done and still have plenty of time to be a real person by fostering relationships and pursuing your passions. One of the most important skills to develop as a student is the meta-cognitive awareness that one has been studying so much that one's brain is saturated and thus, any more studying will be uselessly unhappy and unproductive time wasted: don't bang your head against a wall.
Don't allow schoolwork keep you from doing what you really enjoyed as an undergraduate. Take advantage of volunteer/community service activities.
I prefer to do all of my shopping at farmer's markets and at the pockets of walkable local shops in Mission, Westport, 39th St. West, Westside, River Market, Waldo, and Brookside. The excellent public school system in Johnson County is also commendable.
Live close to campus and walk or ride a bike. Research shows that driving while commuting is people's least favorite time of day. Also, exercise/physical activity helps you to be a better student because exercise increases neurogenesis (the formation of new neurons) in the hippocampus, which is the portion of the brain responsible for new memory formation.
39th Street has a cornucopia of wonderful options — Friend's Sushi, Room 39, Rocc'n Morrocan, Smokehouse Burgers, Po's Dumplings, Mud Pie (coffeeshop), India Palace, Fric & Frac, Aladdin's Café, Blue Koi, Genghis Khan, Thomas, D'Bronx Pizza, and Minsky's.
