Wage peace, not war!
Be proactive; peace is won not granted. Peace is actively kept, it's not the status quo. Be a peacemaker! Keep the peace, be a proponent of peace, find peaceful resolution; resolve, don't take revenge, forgive, don't fret, give, don't keep grudges, actively seek peace and pursue it.
“As much as it depends on you, live in peace with everybody” – Paul
