Thanks. I upvoted you because this is all great advice. I'm politely going to decline it though. Not because I don't think it's valuable but mostly because I already have alternatives to achieve those results that I know work better for myself.
Unfortunately right now I don't have the time to follow through with most of it. Life happens, and right now it just happens to be happening more or less all at once. Urgency trumps priority.
Furthermore, I'm a night owl. I have at different times in my life tried to change it. I followed all the advice I could find (including a lot of the things you mention). Ultimately, if I have to wake up early in the morning for work, I might end up with a cycle of 8h on the first night, with some luck another 8h, then it goes down to 6-5h, 2h and in some occasions an all nighter to top if off.
My current sleep deprived cycle is one of relatively regular 5-6h per night. It's not very good but mostly because of the time I have to be awake.
If I could wake up at 9:30-10:00 every day, I would be able to sleep those 5-6h per night and be in top shape. I know because I've done it for a few months in the past. I was at top physical and mental shape, consistently.
Waking up at 7:00-8:00, even if I could sustain 7-8h per night, I'd still be sleepy, tired and unfocused for the most part. My brain suffers and so does my body.
At this point I just decided to accept light sleep deprivation vs. the worse alternatives.
