Sunday nights waking up for Monday, are usually the shortest ever, day break comes so quickly. I usually set my phone alarm at exactly 7 am but we both know I get out of bed at 7.50 am for a class that is scheduled at 8 am and this is how it all goes down.
As I said my alarm is set at exactly 7 am to get ample time to prepare for an 8 am class but there is a reason as to why there is a snooze time in any alarm activated device, so I personally usually have to do this. So the moment I hear my first alarm ring I open just one eye just enough to allow me reach my phone and set a snooze of a 30 minutes interval.
