Tottaly agree, we have to have some sort of balance between work and rest, otherwise we will and up fuked :)).

I did this a lot, wake up at 6 am and working until 2 am :)), it usualy goes ok 1-2-3-4-5 days, but after i became a zombie for some days. Now i sleep a little much longer( 6 hours), i exercise, read between the work for a little rest and i put on my planner everyday, 1 hour of doing what i desire, tv-show, music. Usualy when i feel tierd i do that for recharging my bateries and it works great for me till now.

I recomand you to try that :)

Thank You!
