Seriously; sleep is really absolutely necessary (no compromise). (At least for me.)

Without it; performance will drop, as well as health & lifespan... (I will not play a fool...)

I will sleep for no less than eight hours; unless there are really urgent timelines to meet; where I will have to go with less sleep for that particular day...

Sleep is also very rewarding & refreshing. (It is probably the best medicine & cure.)

According to some articles; while you are sleeping, the mind actually solve its problems - which would otherwise be difficult to solve when you are awake...

There is some magic performed in your mind & mental state while you are asleep; which benefits & increases the potentials of your mental & physical state... (Definitely you will be a much happier & joyful person...)

Regards.
