If you see your time pass by and your life go, and you have not produced anything worthwhile or beneficial, and you do not find any blessing in your time; then be mindful that you do not fall in the following statement of Allah:
وَلَا تُطِعۡ مَنۡ أَغۡفَلۡنَا قَلۡبَهُ ۥ عَن ذِكۡرِنَا وَٱتَّبَعَ هَوَٮٰهُ وَكَانَ أَمۡرُهُ ۥ فُرُطً۬ا
"And do not obey one whose heart We have made heedless of Our remembrance and who follows his desire and whose affair is ever [in] neglect." (Qur'an 18:28)
Your productivity can be directly proportional to the amount of Qur'an you read.
