To get up early

I don't like getting up early. I had tried many ways to get up early. I regret that they were all unsuccessful.
One way was that I bought an alarm clock with a loud ringing noise. I was used to the bell after a week, I wasn't awaken by the sound.

Another way was that I placed the alarm clock far from my bed. One morning when the alarm went off, I got up and I stopped the clock, but I went back to sleep.

Another way was that I slept early. I assumed that I couldn't get up early, because I was short. Although that wasn't the reason why I couldn't get up early. I haven't yet found a way to get up early.
