Late to bed, late to rise, makes a man healthy, wealthy...

I fundamentally disagree with Ben Franklin on the following point:

"Early to bed, early to rise, makes a man healthy, wealthy, and wise."

I offer to you, a different approach, if your work environment permits it.  (Some places are just set on imposing the 9-5 style, if you are able to break out of the mold, do so, if not, follow Ben's advice).

I'm a night-owl.  And I don't plan to change, because I am most productive after everyone has gone to bed, where I have a nice large chunk of quiet time to write.

And I never have to worry about interruptions.

Now, some people take the alternate approach, where they do all their writing in the morning.  And if that works for you, great!

However, if you find the mornings too distracting (or groggy!) to get in your quiet, work time.  

Flip your schedule.

Optimize!
