CC Antya 18.11

dvādaśa vatsare ye ye līlā kṣaṇe-kṣaṇe
ati-bāhulya-bhaye grantha nā kailuṅ likhane
Word for word: 
dvādaśa vatsare — in twelve years; ye ye — whatever; līlā — pastimes; kṣaṇe-kṣaṇe — moment after moment; ati-bāhulya — too abundant; bhaye — being afraid of; grantha — book; — not; kailuṅ likhane — I have written.
Translation: 
So as not to increase the size of this book, I have not written about all the Lord’s pastimes, for He performed them every moment of every day for twelve years.
