Michał andZawadzki
Senior Consultant

Having a limited number of words to describe myself I choose...that is one of the keywords, among decide, like, wonder. There are many others. Working with people, I value being aware – of a person, a group, and also of words being used. I think of them as a code passing through our minds – all that is within the light of consciousness shapes our experiences and reactions towards the world. So, what do you choose?
