Fasting reminds us about, and helps us to prepare for, death. Don't wait for your evening, might die before. Be always packed and prepared. Ramadhan, we're always thinking quran, sehri, leave sins, Fajr jamat, Dhikr, nafl ibadat etc, routine, not wasting time, ie prepare for death. So continue ramadhan routine after this month, until death. Only difference is no fasting. Don't restart sins. And if sin during Ramadhan, waste of time, just hunger and thirst. Leave sins in Ramadhaan, then continue to leave them afterwards.
