Wabi sabi is a Japanese art and philosophy of imperfection. Wabi sabi will free you from perfectionism. Research suggests that (most) people feel more comfortable and relaxed in slightly imperfect environments that may look a bit old, worn out or even shabby. The irregularity and, to some extent, fractality make us feel more relaxed and give us permission to be ok with imperfection and the transience of things.
