Dealing with emotions

How can we put our emotions aside when in the midst of a situation? time and time again I have thught that we need to stay professional in our approach, stay calm, stay real to our faith and our calling, and yet, we face al sorts of situations in our work. I wonder what strategies Jesus put in place, so he remained faithful to his call, without getting overly angry, frustrated annoyed with the people aorund him. How do we continually show that unconditional love to our young people, and let them know, that whatever the situation, they will always be loved?
