Buhari spoke during the opening session of a two-day Presidential Retreat for the 36 ministers- designate at the old Banquet Hall of the State House, Abuja.
The theme of the retreat is: “Delivering Change: From Precepts to Practice.”
The President also told the ministers- designate to observe the rule of law and shun impunity in the conduct of government activities.
Stressing that they must count themselves privileged to have been chosen to serve among millions of Nigerians, he said the retreat was aimed at getting them acquainted with the direction of his administration.
Buhari also reminded them of his campaign promises of fighting corruption, insecurity and revamping the economy.
He also charged the ministers- designate to work together as a team.
While reiterating his resolve to diversify the economy, he said their achievements should be counted based on the number of Nigerians that are moved out of poverty.
“Avoid wastes and conserve resources,” he said.
He told them the official channel of communication between them and the Presidency in line with the requirements of the Presidential system is through the office of the Chief of Staff.
