I’ve been both, the balance is pretty good these days.
Yes, you can modify your sleeping habits.
It will just take discipline to get started. Probably going without sleep so you can regulate going to bed earlier and set the changes in motion.
‘They’ say it takes 3 weeks to make or break a habit..but, it can be done.
You are re-programming your bio clock to a new setting and that will take some adjusting.
I have always popped out of bed and been ready to start chattering away, my brain wakes up quickly, but my body is taking longer these days. lol
I go to bed sometimes, really early in the winter, but, regardless, I always wake around sunrise. Sometimes, like now in mid-summer, I usually stay up til at least 11, sometimes midnight or later, I still pop awake at sunrise, but I will dash out naked to the barn at 5:30, let the animals out and then go back to bed til maybe 7ish.
I do have a really chill 11 to 5–6 work schedule, but, I have farm pets that are screaming to be let out of their barn at daybreak. Not to mention the ‘neigh-bors’ the herd of mules and donkeys that sound off for hay at the first light.
As long as I get my 8–9 hrs. a few times a week I’m good.
I do like winter though when I get lots of good sleep.
