Haha I've just taken the try and do more with only 4 hours of sleep a day. I know this won't last long as after 2 days I can already feel it catching up to me and it will eventually start effecting my work.
I've also cut back on some of the things I'm involved in and communities I'm active in and more of just someone who checks in every now and then.
With all the options it does force you to prioritize what you enjoy the most and make your overall experience more enjoyable in whatever it is you enjoy.
