<prompt> Human: Im 18 years old and will be attending college this fall, probably premed as a neuroscience major or prelaw. My college has basically a card that I will use for on campus stuff like laundry, etc. I have a job and I am earning about 150 a week during the summer. The rest goes directly to pay to college tuition. I also have a couple of loans that I am using if that makes a difference. What are some good practices that I should keep in mind during college? Should I have a debit card or credit card? Ive heard that you should keep a credit card with a cheap netflix subscription on it in order to build up credit for when you graduate. Is this a good idea? Or are there any other things that I should do?  <response>: Learn how to make yourself food, and get used to eating leftovers instead of eating outfast food. Also, learn how to shop: buy bigger quantities if you can store them, learn what you will actually eat before it goes bad, etc.That is, by itself, the biggest money sink for most people, including those who make good money.
