Efficiency is very often confused with effectiveness. In general, efficiency is a measurable concept, quantitatively determined by the ratio of useful output to total input. Effectiveness is the simpler concept of being able to achieve a desired result, which can be expressed quantitatively but doesn't usually require more complicated mathematics than addition.

 

Efficiency can often be expressed as a percentage of the result that could ideally be expected, for example if no energy were lost due to friction or other causes, in which case 100% of fuel or other input would be used to produce the desired result. This does not always apply, not even in all cases in which efficiency can be assigned a numerical value, e.g. not for specific impulse.

Early risers get a lot of good press: They are supposedly more productive and possibly better problem solvers. But after a month of forcing myself out of bed at 5 a.m., I learned that getting up early isn't always the best thing for you.

 

I’m a morning person, and most days I’m out of bed by 5:45 a.m. I usually have 15 minutes before the rest of my household starts to wake, and I use this time to enjoy a cup of tea as well as the stillness of the morning. I look forward to this time so much that I wondered, What would happen if I expanded the 15 minutes to an hour?
