"I stopped doing any kind of work in my dorm room at college and only did it at the libraries. Not only did I become way more productive, but I enjoyed being in my room a lot more. It’s way more comfortable (and easier) to fall asleep when you’ve taken a 15-minute walk home then when you’ve been working at your desk in the same room for 4 hours."
Today, I don't even need an alarm clock any more, I just wake up before it anyway.
