Another quote from N.T. Wright on a different topic:
Jesus is… the one who would encourage us to pray not only that God’s kingdom would come on earth as in heaven, but also that God would give us this day our daily bread. Many Christians fail to appreciate and appropriate this personal concern that their Lord has for them. One does not hear of people being rebuked for asking too much, or too frequently.
I forget this all the time – I forget our Father never gets tired of hearing from us.
