This is an internet site of Institute for the People and Changes (In-PC), intended for English-speaking citizens.

Inside it, you are reading now a page containing some information for its founder and manager – Roumen Krastev.

Not only manager but also – author of most articles and initiator for new activities.

All new things initially are ideas in the minds of people, who dream to make changes, do invent new and useful things.

Psychologists are trying to understand and explain how the human mind works.

Sometimes there are distinct people, who are not professional psychologists, but they have interests in psychology, human behavior, activities and achievements.

So, I – Roumen Krastev, am such human, I have such interests. I still work as a scientist in the Institute of Mechanics at the Bulgarian Academy of Sciences (IMech-BAS). However, there is not possible for me to accomplish all my dreams and intentions.

So, in 2017 I have founded Institute for the People and Changes, as a legal entity for them. There are a few internet pages and social profiles in Bulgarian language, because of its activities. And this page,, is designed for English-speaking users and activities.

At the beginning of 2021, I supported one site –, where I published articles about how to make balanced improvements in our life. Unfortunately, it was hosted in a bad place and In the summer I decided to close this site. Its content was not lost, I have it as blueprints in English and also as pdf articles in Bulgarian language.

In the fall of 2021 I think to focus my efforts on my activities in IMech-BAS and also on the site The last was made for the promotion of a book that contains all articles about the balanced improvement of life, however – in Bulgarian language.

Thank you for your interest in me and my enterprises.
