Interview with Stephen J. Dubner, for 'Freakonomics Radio' podcast (24 March 2010)
Context: Within my first meeting when I proposed to introduce the flat tax in Estonia they looked on me as I am a little bit crazy. And asked “do you know something on the economy?” and I answer “economically, no not so much.” But I think this is a great idea because it looks to work. And I didn’t know then that I would be the first one to see this, but I introduced it. I was 32, I was young and crazy, so I didn’t know what is possible and what's not, so I did impossible things.
