There is no one that can share your responsibility. It it is your responsibility you must carry it on and you must be responsible for your actions. At the end of the day we all are being challenged, sooner or later, by our destiny. And it's up to us to make all the difference in this life. If not you, who else?

When I was on an American show in 2015, I tried to talk about the threat Vladimir Putin posed to the free world. The interviewer said, "Wake me up when he takes over Poland." We heard something similar from years ago and we ended up with World War Two. Putin decided to skip Poland and went straight to Wisconsin. Putin is at war, a hybrid war, with the free world. His domestic propaganda is based entirely on a strong man challenging the free world. When the demonstrations around Russia began, the harsh response was because it was more important to show strength.

Nervous energy is the ammunition we take into any mental battle. If you don't have enough of it, your concentration will fade. If you have a surplus, the results will explode.

I learned that fighting on the chess board could also have an impact on the political climate in the country.

Many so-called pragmatists want nothing to do with space exploration or other kinds of ambitious endeavours that don't have a clear payoff. This mentality is hugely damaging to our success as a civilization. Our desire to understand the universe is kindled by curiosity and wonder, and this has fuelled countless scientific breakthroughs.

Russia's inclination toward authoritarianism undoubtedly strengthened the leaders in Azerbaijan, Armenia, and Kazakhstan, as they are afraid of normal democratic procedures.

Vladimir Putin is the wealthiest man on the planet, for sure. But this is different to the wealth of a Bill Gates or a Warren Buffett, a Carlos Slim or a Sergey Brin. They stay wealthy whether it is Barack Obama or Donald Trump in power. Putin's wealth depends on him staying in power. It is all about controlling the budget, the hard currency reserves and keeping under his thumb the oligarchs who cannot move their money without his permission. It is something close to a trillion dollars that he can control and move.
