At lot of it comes down to attitude. I remember a coach I heard responding to someone who said “I find it impossible to get out of bed when my alarm goes off. All I want to do is hit the snooze” and the coach said something like this, “Really? All it takes to get out of bed when your alarm goes off is to put your feet on the floor and stand up. If you woke up completely tired in the middle of the night but your bed was on fire I bet you would have no problem getting right out. That means you can easily get out of bed as soon as you decide its what you need to do. Decide the night before, when that alarm goes off in the morning you will put your feet on the floor and stand right up.”
