Regarding the late owl or basically staying up at night working in front of the screen(s) let me tell you this. Have done so for ages and it definitely hurts your health big time. One of the key things that helped me change this was this tool called "f.lux" that removes the blue light from your screen after sunset. This leads to your body and mind being able to come down and start sending sleep or rest signals from your brain to your body and also to your mind. This leads to being able to fall asleep faster, have deeper and more solid sleep and thus also waking up earlier and actually feeling fit.

When I first read that I would not believe it. Now I have tested this "f.lux" tool on two 1920x1200 dell u2412m screens that I do dev work on and oh wow what a change!! Even if I want to work late I am simply so tired after a day of work (and I know how you can always squeeze in one half hour to tweak code) and the screen does not keep me awake any more, so I hit the sack and oh wonder the next day I simply cannot stay in bed any more and feel wide awake with the sun coming through.

This is what humans natural rhythm has been for ages and will also always be like that, at least for the next couple million years when we get a DNA update but that is an entire different story. Our brain and body is tuned to the sunlight and when you have sunlight your brain sends out signals that keep your mind and body awake. So does your screen, the light during the day is like sunlight, when you sit at it at night it will keep you awake for sure.

Why am I telling you this? I have two kids and was always tired during the day, thinking I don't get enough done, feeling bad that I did not really have enough energy for my kids nor my girl. Now that I sleep regularly and deep I get so much more done during the day am happy when the sun sets and know the next day I will have power to tackle the next level on my to do list. I don't want to post a link, but if you search for "f.lux" you will find it for sure. There are also some proven scientific studies about this and how blue light affects sleep and what not. For me this was a real eye-opener, pun intended.

You will see if you shift your work rhythm, sleep at night and work during the day you will be super happy to snug up to your wife at night and will get more stuff done during the day since your mind and body and mostly brain will not have to copy with not having had rest but still trying to deliver good intelligent output. You see what I am getting at? Sleep is terribly underrated in today's society so please you also do not make that mistake. Sleep at night and work during the day. It will give you a real boost. Give it a shot. You can always go back to the old days if you don't like.

Naturally having more energy during the day I am sure you will have have more time for your relationship and actually also feel more happy about yourself as a whole. You might also find some clues inhttps://wptavern.com/tackling-depression-in-it about this. Sadly this article does not mention the "screen factor", might have to post a comment there too about this. most people in IT have no idea what all this bright light does to them.

On the "Research" section of that "f.lux" site is a PDF linked: http://www.pnas.org/content/112/4/1232.full.pdf Go have a read and see what you are missing. I promise you once you sleep well at night you will feel better about yourself during the day and get more stuff done. And this comes from a chronic night-worker late owl that now is an early bird and loves life even more. It will all come into place.

To finish all this, I am sure "You Can Do It" https://www.youtube.com/watch?v=C75UOhvPMbs it just shouldn't be working at night.. :)
