Finding the time to write

As a busy college student I always have a hard time finding the time to write. There's always some new problem set to do, or book to read, or friend to hang out with. Real life just keeps getting in the way of my fictional one. This is hard because everything I've learned about writing and publishing has taught me that the key is persistance. Quantity is almost as important as quality.

The only thing I've found that really works is putting aside 30 minutes of every day to just turn off the internet, turn off my phone, sit in my special spot on the couch and write. Cutting out all the distractions of the outside world, and limiting writing time to a short, set interval makes the process a lot easier, and a lot more manageable. What do you all think? How do you find the time to write?
