Biblically speaking, we are soldiers engaged in warfare. Our weapons are not physical, like guns or grenades but they are more powerful than their physical counterparts.
Engage the enemy.
Prayer is an exercise in discipline, faith, and trust. You can't fight unless you trust your Commander in Chief, Jesus Christ. The enemy uses people to carry out his evil plans but we are fighting a spiritual battle that can not be won with human devices. Our best laid plans fail to bring lasting reform. Only God can change a life and he tells us, his soldiers, to pray for our enemies, for those who persecute us, for those who hate us and for those who are eternally lost. The enemy will use whatever obstacles he can to distract us from this mission. When you drop the ball, and chances are you will, pick it up again. Discipline is not about perfection as much as little steps of obedience. "Devote yourselves to prayer, being watchful and thankful." (Colossians 4:2)
