About cleanliness ... I value cleanliness. I try to clean my flat every day, because I hate messiness. Keeping my space clean helps me stay focused. My desk is the place where I study a lot. It's extremely important for me to have a clean workspace. If my desk is a mess I always get distracted from my work. I try to be a minimalist. Minimalism makes my life easier. This approach to life reduces time associated with cleaning. Most of my textbooks are E-books. I prefer using only computer to learning from classic printed books. It's much easier and faster to find needed information and doesn't require additional space for all those books. I'd appreciate any feedback from you :)
