Katharina also regularly shares photos of the fine wine and expensive taste she and her friends have.

They like to indulge in Foie Gras, champagne and canapés.

But despite finding the crampt dorm life of a student hard to adjust to, she maintains studying abroad was the “right decision” for her, even if she still tags photos saying she is “homesick”.

She has won several awards on her horse Belamour at the European Junior Riders Championships.

When asked about her family wealth, she said money does not always guarantee success.

“I feel a great responsibility. In a way I think that I have not made ​​me deserving of this, while I want to help develop Ferd and make it even better,” she said.

“Finding a way to give something back, I think is difficult. The fact that my family has resources has given me many opportunities, especially in the riding, because it requires a lot of capital.

“But it is not enough to have money to succeed.”
