Loving many people can hurt. There's no way around this one. An accountability partner or group is a good place to deal with these issues. I can't stress this enough. Working with international students means spiritual warfare, it's on your knees that the battles are won.
Prayer is indespensible to effective leadership.
Rely on the Holy Spirit. Unless the Lord builds the house, the builders labor in vain. This is the starting point. God asks us to do our part, but we must in turn rely fully on him. In the end, He's responsible for the results, liberating us from the fear, stress and pride that so often trips us up.
