I think waking up early is like the biggest challenge in my life. A single alarm can never wake me up successfully, and till recently, I have changed to a new phone, with multiple alarms function. It is really the greatest invention in the world.

So, I set my alarm at 0700, 0730, 0800…till I wake up! And, after a few days of experiment, it does work for me! How do you wake up?
