How many times do I need to relearn this fact of life? Last night I tried to correct a troublesome Excel spreadsheet until I gave-up in frustration. This morning, I fixed it in five minutes.


Sleep that knits up the ravell’d sleave of care,
The death of each day’s life, sore labour’s bath,
Balm of hurt minds, great nature’s second course,
Chief nourisher in life’s feast.

–Macbeth (2.2.46-51)
