The governor spoke on Monday at the Government House Port Harcourt when he swore-in five commissioners and one special adviser.
Governor Wike said: "We are coming to the end of our first term, but you can still make a difference.
"Once you have the passion, you can still make a difference. It is a privilege to serve the state and you have to make it count. Don't waste the opportunity".
While charging the newly sworn-in commissioners to take their jobs seriously, Governor Wike asked them to conduct themselves in acceptable social manner.
He said: "Take your job seriously and don't involve yourselves in illegality. As a commissioner, don't place yourself in a compromising position".
The governor charged them to always ensure that they place the interest of the state above other considerations in their activities.
He announced that Dr Zaccheus Adangor has been appointed the Honourable Attorney General and Commissioner of Justice of Rivers State, while Mrs Aguma is now the Commissioner for Social Welfare.
