I felt like adding my own experience to the great answers you are getting, because I thought it might help you to know that other people have been through this and managed to find a better balance :)
When I was an apprentice, I had a very difficult last year at school. I hated what I was doing there, and so I got in the habit of waking as late as possible and to live like I had lost my grip on my own organisation: I was always late for everything: class, but also personnal appointements and such.
When I finished school and got back to my company, I started being late too, and having a lot of trouble to wake up early. I had gotten into the habit of going to bed late, and I felt like I could never go back to waking up early.
Arriving half an hour late almost every day bothered me a lot, because it made me feel like I was unworthy of my job. I was afraid that my team would find me unprofessionnal and demotivated, but I felt so helpless about it. I was trying to compensate by finishing later, but this made me feel always guilty, and I was counting every minute I had "stolen" to be able to give it back at the end of the day.
After a few months like this, I started to try to arrive ten minutes before the hour I was supposed to arrive. So I started waking up 40 minutes earlier. At first it was hard, because I had trouble to find sleep going to bed earlier.
But the feeling of being on time relieved the guilt so well that I tried to stick with it no matter what, even if it implied sleeping less some nights.
I also noticed that I was being much more efficient when I started work earlier (I know it's not true for everyone, but if it is your case, it might be a supplementary motivation).
After a few months, my sleep routine has shifted and I don't have trouble anymore going to bed earlier. I feel much more relaxed because I arrive on time. This also affects my personal organisation: I am not late to appointements anymore, and I make sure to hit deadlines.
In other words, it was hard, but fighting for a few months to find a schedule that fitted me better was totally worth it, professionaly and personnaly speaking. I also have a much better self-esteem than I had back at school.
I hope this helps you to find motivation and find your own balance at work :)
