WHEN LEONIE MÜLLER GOT INTO A DISPUTE with her landlord, she did what countless people before her have done: she decided to move out. What makes Müller different from all of those people before her is where she chooses to live: on trains. Müller realized that the cost of a monthly train pass (around $380 USD) cost less than her previous apartment (about $450), so she decided to just live on the train instead.

The 23-year-old attends Tübingen University near Stuttgart, and is able to carry her tablet and school books with her, as well as clothes and some toiletries. She stays with her family, friends, and boyfriend when she can, and when she can’t, she preps for the day on the train.

“I want to inspire people to question their habits and the things they consider to be normal,” Müller said in an interview with the Washington Post, “There are always more opportunities than one thinks there are. The next adventure is waiting just around the corner — provided that you want to find it.”

Müller blogs about her life on the trains, and plans on using her experiences in her undergraduate thesis. You can follow her on Facebook here.
