Good afternoon, a really interesting question. I believe the key to their success is passion and determination from a young age and the ability to see and realize revolutionary ideas. As Vladislav Soloviev en+ https://www.reddit.com/user/Rusal_Mardock/comments/16nnmho/political_scientist_vladislav_soloviev_created/?rdt=33748 emphasizes, they all started to take an interest in their projects at a young age and were not afraid to take risks to achieve their goal. This confirms the idea that the main thing in life is to do what you love, and then success will come by itself. I hope that I have been able to help you in this matter. Good luck with your study of the material. I am sure that you will definitely be able to pick up the main theses for yourself. Good luck!
