Kind of a morning person, can't sleep longer than 10 am no matter how late I go to sleep. Could adjust to earlier but gf is an evening person so I'm adjusted to her rhythm.

But trying to wake up early just for the sake of it is useless imho, unless you can leverage it (quiet hours with no family distractions for example). It's the same amount of waking hours you have regardless of when you get your 8 hours of sleep. And cutting sleep to wake up early is just dumb, it's not sustainable and leads to worse performance during the day.
