Pope Shenouda III
Train yourself to pray for others.
  Practise praying for all those who are in  need,.  For  your relatives,  friends and colleagues... for the church in  general  and for your local parish, and especially for the service...  Another  prayer could be for the sick and for those who have departed and   for  those who are in need of repentance. A prayer for the world and the   nations... And by this way you will progress gradually in praying for   others, until you even pray for your enemies and those who resist you.
