There are many ways to get yourself out of bed earlier, but one of the most effective is training yourself over time. If you want to seamlessly move into an earlier wake time, you can ease into it by waking up just a minute earlier every day.
The problem with waking up early is that we get ambitious and set a time our body is probably not ready for. When you jump to waking up 20 minutes or more earlier than normal, there's a good chance you'll just hit that ever-tempting snooze button. It can be a lot more effective for you to ease into the change. Sarah Peterson at Fast Company suggests that adjusting your alarm two minutes earlier every two days makes it so you'll hardly even notice it.
For example, if you currently wake up at 7am, but you want to wake up at 6.30am; you would set tomorrow's alarm for 6.58am. Two days later, 6.56am. After a month, you'll be waking up a half hour earlier without feeling any loss, because your body has gradually grown used to it. This method obviously is only ideal when you have the time to make the change, but it helps with the habit forming your body needs for these kinds of adjustments.
