Keep up the fight! Today is the midpoint of Lent.

From the Mozarabic missal, via The Liturgical Year:

Looking forward, dearly beloved brethren, to the hope of the Passion and Resurrection of the Son of God, as also to the manifestation of the glory of our blessed Lord and Saviour Jesus Christ : resume your strength and courage. Be not daunted by the labour you have to go through, but remember the solemnity of the holy Pasch, for which you are so ardently longing. One half of holy Lent is over: you have gone through the difficulties of the past, why should you not be courageous about the future fast? Jesus, who deigned to suffer fatigue for our sake, will give strength to them that are fatigued. He that granted us to begin the past, will enable us to complete the future. Children! He will be with us to assist us, who wishes us to hope for the glory of his Passion. Amen.
