People inspire me through their work conversations with them and sometimes just their presence

Dirk Hordorff
Probably one of the most important people in my life. Having experienced the tennis world alongside on of the most influential characters in that sphere has taught me more than I could have ever imagined. Dirk opened my eyes in so many ways
- I miss you Dirk, RIP-

Rainer Schüttler
Despite his success one of the "purest" characters I have ever encountered. He is a role model for any human being

AKI
My first coach, I admire him so much for transmitting his passion for TENNIS and marking me for the rest of my life. -RIP AKI-

Paulo Coelho
His books have always given me food for thoughts

Morgan Housel
Same as Ever & Psychology of Money

Chris Froome
The Climb

Prof Steve Peters
The Chimp Paradox

Gay Hendricks
The Big Leap

Simon Sinek
More than just his books, also his courses

Ritch Litvin
A great Coach, that integrates a lot from the people above in his coaching
