This is a really effective way to get

This is a really effective way to get a lot things done. In summer 2009 I used to wake up before sunrise and absolutely loved it. To this day, I still wonder why I did not continue doing it.
My 2 cents:
Make sure you have something good (preferably healthy) to eat readily available when you get up. It should be something that does not require more than 10 min of preparation. Otherwise things tend to get a bit boring.
If you happen to wake before sunrise. Take mini walk in you garden or backyard and catch those 10 - 15 minutes of sunrise. It will absolutely super charge you for rest of the day.

EDIT: Let's admit that we all have a small nest at home specifically for work or related activities. Move this nest out of your bedroom. Keep your laptops, iPads, PCs or any such devices out of your bedroom. Switch off your phones during nights and do not switch them back on until after your morning sessions.
(PS. My uncle is a neurologist and he tells me that for people who work during day and rest during nights, certain hormones are secreted in the mornings that help us in staying fresh and awake. The catch is that they are only secreted if you wake before or around sun rise time.)
