Work for only 3 hours a day, but everyday
Historically, working 24 hours a day (I include sleep because after a certain number of hours you even dream of code or your business) for 1 year typically accomplishes more than working 3 hours per day for 8 years.  Or 1.5 hours per day for 16 years.  There is just some kind of economy of scale.<p>---------<p>EDIT:  I got downvoted.  Come up with whatever standard of productivity you want (ANY standard that you want) and adduce a single human who in 16 years times 90 minutes per day accomplished more than I can find a counter-example of someone doing in the same field in 1 year.  1 year of 24 hours a day strictly dominates 16 years of 90 minutes per day, and you cannot find a single counterexample in any field from any era of humanity.  Go ahead and try.<p>oh and by the way, in 1905 Einstein published 1 paper on the Photoelectric effect, for which he won his only nobel prize, 1 paper on Brownian motion which convinced the only leading anti-atomic theorist of the existence of atoms, 1 paper on a little subject that &quot;reconciles Maxwell&#x27;s equations for electricity and magnetism with the laws of mechanics by introducing major changes to mechanics close to the speed of light. This later became known as Einstein&#x27;s special theory of relativity&quot; and 1 paper on Mass–energy equivalence, which might have remained obscure if he hadn&#x27;t worked it into a catchy little ditty referring to an &quot;mc&quot;.  You might have heard of it?  E = mc^2?  Well a hundred and ten years later all the physicistis are still laying their beats on top.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Annus_Mirabilis_papers" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Annus_Mirabilis_papers</a><p>Your turn.  Point to someone who did as much in 16 years by working just 90 minutes per day.<p>Closer to our own field, Instagram was sold for $1 billion about a year after its founding date, to Facebook.  Point out anyone who built $1 billion in value over 16 years working just 90 minutes per day.
