The Christian life should always be focused on God. I love this story about the focus Abba John the Dwarf had:

A camel driver came one day to pick up some goods and take them elsewhere. Going inside to bring him what he had woven, Abba John forgot about it because his spirit was fixed in God. So once more the camel driver disturbed him by knocking on the door and once more Abba John went in and forgot. The camel driver knocked a third time and Abba John went in saying, ‘Weaving – camel; weaving – camel.’ He said this so that he would not forget again.

You must admire this level of dedication to God!
