I realize that the strivings of the Polish people gave rise, and still do so, to the feelings of understanding and solidarity all over the world.

I belong to a nation which over the past centuries has experienced many hardships and reverses. The world reacted with silence or with mere sympathy when Polish frontiers were crossed by invading armies and the sovereign state had to succumb to brutal force.

We have travelled so far in our technical advancements that we are no longer located in our own countries.

I cannot stand for more than half an hour in one place.

The 9/11 attack itself played out around the world, with planning meetings in Malaysia, operatives taking flight lessons in the United States, coordination by plot leaders based in Hamburg, and money transfers from Dubai - activities overseen by al-Qaeda's senior command from secure bases in Afghanistan.

I like to have a team environment where I can go anywhere and not threaten management.

I love everything about football. You can learn so much from it, from leadership qualities to discipline. This sport involves every kind of emotion.

When I came to the United States in 2004 to attend university at Stanford, I was instantly inspired by the stories and advice from startup leaders in Silicon Valley and beyond, who had endeavoured to create new opportunities and improve lives around the world.
