I was wrong. I shouldn't sleep again when it's only 20 minutes to work even if the
distance between company and my living place is only 10 minutes. I should't deceive myself that I will awaken up by then. The result is I was slept until 10:50.
It's my bad habit all the time. I always ask too little to myself so that caused such consequence. This time I decided to deeply reflect on my wrong behavior and made up my mind to avoid its recurrence.
I promise won't be late again for this reason. I have realized my wrong and been deeply reflecting on it.
