I am a quite discipline person. I would make sure I attend all of my classes on time, but last week was different.

I was staying up late until 2 a.m. which was very unusual for me. Then I set my alarm to 5 a.m., so I could wake up early for my morning class. I didn’t hear anything that could’ve woken me, even I couldn’t hear my blasting alarm. As a result, I woke up at around 6:45 am which was a quarter to my morning class. Being in hurry, I forgot to put my homework into my bag that morning, the very homework I spent the night staying up late until 2 a.m.

From that day on, I promised myself not to do the same mistake by not staying up late again if the next day I’m having a morning class.
