Now, call me an edgy jerkoff for emulating whiterose from mr. robot BUT
I got a wristwatch that has alarms and I set an alarm for every hour during the time I'm awake and I segment my tasks into 1h chunks. Even with work.
I got a paper calendar and wrote down important dates and shoved everything else into my regular calendar.
I have a short attention span and that helped me a soykaf ton.
