“Press the damn button that changes the chapter, that takes you out of ‘it doesn’t matter’ and puts you into ‘this is how I want it’. Because life is too short to spend it where you don’t fit — and so big and beautiful when you fill it with what inspires you. This is the motivation this book gives for our professional lives. Thank you, Spyros, for the inspiration!” Maria Bakodimou, Presenter, Personal Development Consultant

“Spyros made, with quite some difficulty as the right decisions should be, the choice that ultimately changed his life. This book contains the essence of a personal journey and at the same time opens your eyes and mind. Let’s remember that chasing our dream is not just a desire, but an obligation to ourselves.” Christos Sotiropoulos, Sports Journalist, Founder of SPOR FM 94.6 & Sports Reporting Center

“‘It’s impossible to succeed on your own,’ writes Spyros. And he’s right. But you are not alone. Fortunately, there is the 5-Star Professional. Concentrated wisdom and practical experience page by page. A must-read for anyone who wants to stand out in the modern professional world.” Themis Chasiotis, General Director of Communication and Sustainability, Papastratos

“I have the luck and honor to have known Spyros for years. Honest, direct, broad-minded, hardworking, ambitious, eager to learn, methodical, Spyros combines all the good qualities a professional can have. Above all, though, he is a human being. The 5-Star Professional is excellently written. Concise, deep, comprehensive, true, and realistic. Its 5 Pillars cover all areas related to professional success, but also happiness. It is the manual that will take you to the next level, provided you truly desire it. ‘The more indispensable you are, the less the rules apply to you’—I think that’s my favorite quote. Spyros, good luck with your wonderful book. It is also 5-Star, just like you.” Stefanos Xenakis, Author
