Whatsapp co-founder Jan Koum gave a rare interview to a Russian journalist and it is my favorite read of the day. When asked how the $19 billion dollars sale to Facebook changed his life.

I still live in the same place. I have the same friends, and that is very important. And I have the same job. After the deal with Facebook, 90% of my life did not change.

I am a big admirer of his simple, no-nonsese and low key approach to business.
