How do you tackle lack of discipline?

When I was also student and was at home my mother ensured that I follow a routine. But its been around a decade since I completed my 12th.

Im doing well in my career, thanks to my fear and anxiety fueling me to complete the work in last minute. But its taking a toll on my health.

How do you guys stay disciplined?

[More about my messed up routine:

1. I woke up when I feel like
2. Sleeps around 2-3 watching pron, or reels
3. Eat very less and shitty food
4. Taking multivitamin and unnecessary supplements
5. Not learning anything new
6. Not pushing for a raise or promotion
7. J*rking off 3-4 times a week
8. Say yes to any weekend trip, putting lot of pressure on my physical health
9. Working late nights when deadline is near and not working at all when have plenty of time
10. Dont have any debt, dream or motivation to work for .. And the list goes on. ]

Thanks in advance for your responses.
