With three kids, a puppy and a husband that goes away to work I don't get the chance to sleep in very often. When a chance to sleep in comes along you can bet your bottom dollar I grab it. A sleep in for me is about 8am.
I keep telling myself I should go to bed earlier but I think I am a bit of a night owl and generally don't get to bed before about 11pm.
Do you think as you get older you just naturally get up earlier? All the oldies I know wake up at the crack of dawn even when they don't have a reason to.
When I use to swim before taking the kids to school (this was when my husband worked normal hours) the other swimmers were all retired. I would ask them why they would be at the pool at 5am if they did not have to be and most of them said that they could not sleep in anymore. Great I thought I don't get the chance to sleep in now and by the time I am an old retired woman I wont be able to.
The most effective way to do it, is to do it.
