Without an alarm, I could never wake up on time for something I need to do in the early morning.
Let's day I have to wake up at 9:00 AM.
I go to sleep early, and wake up at 6:25 AM. "No big deal, I still have two and 1/2 hours of sleep." says me, as I go back to bed.
Then I wake up at 6:53 AM. "I can keep sleeping." says me, as I go back to bed.
Then I wake up at 7:37 AM. "Not yet." says me, as I go back to bed.
Then I wake up at 7:54 AM. "Relax, we won't be late." says me, as I go back to bed.
Then I wake up at 8:11 AM. "Almost there." says me, as I go back to bed.
Then I wake up at 8:45 AM. "Just 15 more minutes." says me, as I go back to bed.
Then I somehow wake up at 3:19 PM, despite all of that sleep. "WHAT THE HELL!?" says me, as I get out of bed, tired and confused.
So yeah, I'm glad alarms exist.
