%pylab %matplotlib inline import pint
Using matplotlib backend: TkAgg Populating the interactive namespace from numpy and matplotlib
u = pint.UnitRegistry()
"It just takes a minute"
annual_savings = u.minute/u.day*(5*u.day/u.week)*(50*u.week/u.year) annual_savings.to(u.hour/u.year)
If you spend 4 hours a day doing your job and 4 hours a day automating 1 minute of it, in 1 work year you'll break even on that minute.
In year 2, even if you never automate a part of your job again. You'll have an extra 4 hours/day, doing 12 hours of work in 8 hours.
