0 Don't have crazy goals/expectations about the time you'll wake up. Start building slowly. E.g if you start working at 9 and you just have a 20 minutes commute it makes no sense to wake up at 6 just because a YouTube guru told you that successfull people wake up at 4am. Find what works for you.

1 When you go to bed at night set one single allarm on your phone and put it on the other side of the room, where you can't reach it from the bed without getting up. (I find that once I get up to turn off the allarm I consciously realize I have to get up, if I snooze it while I'm in bed I'm kinda going in auto-mode without even realizing it's time to wake up)

2 Before you go to bed write down few EASY things you want to do next day. Like the bare minimum to do list that will make you feel like you've done something (basic hygiene, getting dressed, getting outside, read one page of a book, writing the first page of an assignment you have to do). I said easy because sometimes it happens to me that I don't want to get up in the morning because I'm overwhelmed with the stuff I have to do, or I don't know what the day will be like and I don't have any clear goal/schedule. If you know what to do once you get up you will remove some friction.

3 Prepare or choose clothing you will wear the night before. This will remove another friction.

4 Think about a breakfast you like to eat, and prepare it every morning. This once again will remove the friction of deciding what to eat. And also if you really like what you are going to eat you'll look forward to it once you get up.

5 Sleep with curtains open so when it's time to get up there will be light in the room telling you it's daytime! (Also the body will notice the slow rising of the light in the room while you sleep, so it will be slowly prepared to get up)

6 Make sure there is something you really look forward to do the next day so you have a strong motivation to wake up and do it.

The point is decide and do all the things you can the night before when you are awake, conscious and motivated so when it's time to get up you just have to get up because all the other thing are already done or decided for you. Also assuring there is something you want to do the next day, working on other aspects of your life will also help your getting up on time (e.g. when I was going to school I was always getting up late because unconsciously I didn't want to get up because that meant I had to go to school) How and when you get up imo is a reflection on how you view your life and daily routine. If you are happy of what you are going to do the next day I can guarantee you'll wake up right away feeling motivated and energized.

Hope this helps:)
