A long time ago I wanted to be a traveller - I've been to about 50 countries and lived for more than two years abroad.

I wanted to become an IT specialist at the bank, but now I run a fin-tech company dealing with new technologies that can disrupt the banks.

I failed a few times in my startups, and now I advise my students how to avoid my mistakes.

I used to read more than 100 books a year, and now others read publications written by me.

I was weak in spelling and grammar. I still am, but I publish at least one book a year.

I was afraid of relationships - now I'm married to a beautiful girl and am a happy father of three.

I was shy and introverted - I think I still am, but I speak in front of hundreds of people (like on the picture, while I was publicly advising a political party).
