no particular order

i use the sleep cycle app to wake me up in the lightest sleep phase

i create a morning ritual of short wins that build momentum
these small tasks also become triggers

you should check out the book "miracle morning" by hal elrod

and the 5am miracle podcast by jeff sanders

make it easy to get to each of the items in your ritual
for instance one of mine is to drink a glass of water when i wake up so i put the water on my desk the night before

wash your face with cold water as soon as you get up...which makes you actually get out of the bed

the biggest thing for me is to have clear tasks outlined beforehand and not just getting up early without a plan....
i find that the days that i don't have a plan outlined are the days that i hit snooze more often
early mornings are great for side projects

edit: oh and going to sleep properly the night before is huge. if you can have a consistent bedtime that will help tremendously. if you can't do that...try to set a time in which you stop using any electronics. if you do have to use a laptop late at night make sure you have flux installed https://justgetflux.com/
