An individual wrote,

I recite one section (manzil) of Dalail al-Khayrat and Munajat e Maqbul daily. However, some days I miss these recitations as a retribution of my deeds. 

Hakim al-Umma Hadhrat Mawlana Ashraf ‘Ali Thanawi (may Allah have mercy on him) replied,

“The section of Munajat e Maqbul are quite concise. There is no reason they should be missed. However, this is possible in the recitation of Dalail al-Khayrat. Recite individual sections over 3 or 4 days, completing the whole recitation of Dalail al-Khayrat in a month.”
