Excerpt from the Book "Secret of the Rosary"
WHEN  THE ROSARY is well said it gives Jesus and Mary more glory and it is  more meritorious for the soul than any other prayer. But it is also the  hardest prayer to say well and to persevere in, owing especially to the  distractions which almost inevitably attend the constant repetition of  the same words.
When  we say the Little Office of Our Lady, or the Seven Penitential Psalms,  or any prayers other than the Rosary, the variety of words and  expressions keeps us alert, prevents our imagination from wandering, and  so makes it easier for us to say them well. On the contrary, because of  the constant repetition of the same Our Father and Hail Mary in the  same unvarying form, it is difficult, while saying the Rosary, not to  become wearied and inclined to sleep or to turn to other prayers that  are more refreshing and less tedious. This goes to show that one needs  much greater devotion to persevere in saying the Holy Rosary than in  saying any other prayer, even the Psalms of David. 
Our  imagination, which is hardly still a minute, makes our task harder and  then of course there is the devil who never tires of trying to distract  us and keep us from praying. To what ends does not the evil one go  against us while we are engaged in saying our Rosary against him. 
Being  human, we easily become tired and slipshod----but the devil makes these  difficulties worse when we are saying the Rosary. Before we even begin  he makes us feel bored, distracted or exhausted----and when we have  started praying he oppresses us from all sides. And when, after much  difficulty and many distractions, we have finished, he whispers to us:  "What you have just said is worthless. It's useless for you to say the  Rosary. You had better get on with other things. It's only a waste of  time to pray without paying attention to what you're saying; half an  hour's meditation or some spiritual reading would be much better.  Tomorrow when you're not feeling so sluggish you'll pray better; don't  finish your Rosary until tomorrow." By tricks of this kind the devil  gets us to give up the Rosary altogether or else hardly say it at all,  and we keep putting it off or else change to some other devotion. 
Dear  Rosary Confraternity members, do not listen to the devil, but be of  good heart even if your imagination has been bothering you throughout  your Rosary, filling your mind with all kinds of distracting  thoughts----as long as you really tried hard to get rid of them as soon  as they came. Always remember that the best Rosary is the one with the  most merit, and there is more merit in praying when it is hard than when  it is easy. Prayer is all the harder when it is (naturally speaking)  distasteful to the soul and is filled with those annoying little ants  and flies running about in your imagination, against your will, and  scarcely allowing you the time to enjoy a little peace and appreciate  the beauty of what you are saying. 
Even  if you have to fight distractions all through your whole Rosary be sure  to fight well, arms in hand: that is to say, do not stop saying your  Rosary even if it is hard to say and you have absolutely no sensible  devotion. It is a terrible battle, I know, but one that is profitable to  the faithful soul. If you put down your arms, that is, if you give up  the Rosary, you will be admitting defeat and then, having won, the devil  will leave you alone. 
But  at the Day of Judgment he will taunt you because of your faithlessness  and lack of courage. "He that is faithful in that which is least, is  faithful also in that which is greater." [1] He who fights even the  smallest distractions faithfully when he says even the very smallest  prayer he will also be faithful in great things. We can be absolutely  certain of this because the Holy Spirit has told us so. 
So  all of you, servants and handmaids of Our Lord Jesus Christ and the  Blessed Virgin Mary, who have made up your minds to say the Rosary every  day, be of good heart. Do not let the flies (it is thus that I call the  distractions that make war on you during prayer) make you cowardly  abandon the company of Jesus and Mary, in whose holy presence you always  are when saying the Rosary. In what follows I shall give you  suggestions for getting rid of distractions.
