Tricks I personally use for better sleep: 1) Fresh air. I live in a semi-rural area, where the air is fresh enough and not very polluted. So, every evening after dinner I usually walk 20 to 30 minutes around my condo or a block in a slow pace (7-8km/h) to give my body a little boost of oxygen. + Before I go to sleep, I open windows in my room for 5-10 min just to get rid of stale air. 2) Instead of bed of nails I do special stretches. 3) Don't eat 2-3 hours prior to bed. Totally agree with you. Also I try to have something light for my last meal. Some salad will do just fine. Besides, when I feel hungry, I drink green or some relaxing herbal tea with no sugar or honey. 4) When my insomnia kicks in, I usually watch something very-very boring like lectures on philosophy or politics. Or listen to some mild voice Twitch streamers. I set Twitch app om my phone in audio mode only, get in bed, turn off the lights, put on my earpieces and it takes me 10 to 20 min to feel sleepy enough.

I read 'The 4-Hour Workweek' by Tim Ferris. And though he has some interesting concepts, ideas and valid points in it, I feel like he is a dodgy person.

Time tracking is a very useful tool to improve your efficiency. But, I think we use too much apps, programs etc in our daily life. So I just use a simple paper notebook. Nothing fancy, but effective.
