I agree. Actually its about knowing when to sleep than sleeping less always, more like when to accelerate and when to brake. I guess that's what Edison did too

I agree. Actually its about knowing when to sleep than sleeping less always, more like when to accelerate and when to brake. I guess that's what Edison did too. Many times over a period what you really need is long stretches of un interrupted time to get something big done. You will have to take a break after that. Come back with a fresh purpose, an new challenge and start again.
