Reading about Chinese architect Xu Tiantian, her work, and architectural acupuncture. In an interview I find this answer–which should be applied the other way around too:
Question: Is there anything that you would like to change in the university system?
Answer: To be more open. Especially for the students in their early years of architecture education, it is really important to open up their minds, to see more architecture and look beyond architects. There’s a lot of inspiration from others, from art, from culture, from literature, from everything, from life in general. So you need to get that as your foundation when you start in architecture.
