Addressing a programme organised by a news agency here, he said due to negative thoughts and negative politics development in the past had been hit, a press release quoting him said.
Stating that some people still indulged in negative politics, Das asserted they would not be successful.
He said the government was run not by slogans, but by rules and intention.
"And this is the reason that when my government came rules were made and implemented in good intention," he said.
Das said his government initiated several poverty-eradication schemes to give the people opportunities to increase income - one of them being two cows for a poor family.
