"My biggest mistake was that in my actions at first there was a lot of idealism, a lot of euphoria," Kravchuk said in an interview with 112 Ukraine.

The ex-president of Ukraine also shared his opinion on how to make the country “happy and rich”. For this, Ukrainians need to move "from the stage of euphoria and bliss to the stage of responsibility, rationalism, common sense, faith."

Earlier, Kravchuk said that the main shortcomings of the former President of Ukraine Petro Poroshenko as head of the country were the desire to become a rich man and incredible careerism.
