I am so excited!
"Rozwoj osobisty czlowieka rozumnego" (link to the publisher's site - MT Biznes) Rozwój osobisty cz³owieka rozumnego - Steve Pavlina - Wydawnictwo MT Biznes
I hope the translation is good! Polish title sounds little funny, it's something like "Personal development of homo sapiens"
Although I have book in English, I decided to order another copy in Polish
