Monday through Friday contains 120 hours and makes up 71% of our lives. I've been thinking a lot about what I do during these hours and whether or not I'm using them as effectively as possible.

Here's the breakdown for me:

54% - Work (65 hours)
33% - Sleep (40 hours)
4% - Exercise (5 hours)
4% - Spending time with friends and family -- in person or over the phone (5 hours)
4% - Chilling out -- reading, watching TV, internet, research, paying bills, etc. (5 hours)

Because a reasonable amount of sleep, or at least rest, is a requirement for me, I'm spending 77% of my Monday through Friday doing something that is more or less involuntary.

If you're anything like me it's crucial that you're getting a BIG return on the effort you're putting into your work.
