So, I record my time tracking by hand, and later I sum it up and divide it out by hand.
It takes me about an hour a week. I regularly get the suggestion that I should get it into a spreadsheet or an application to cut that time down.
By doing it by hand, relatively slowly, I'm forced to turn the implications over in my mind of the numbers.
For instance, I slept 8.2 hours on average over the last 13 days.
If I saw that on the sheet, I wouldn't pay much attention to it.
But... here's how I got there -
6 + 11 + 6.5 + 6.5 + 11 + 6.5 + 2 + 12.5 + 9.5 + 8 + 10 + 8 + 9.5 = 107 /13 = 8.2
Note that there's only two days in there between 7 and 9 hours. Five days were under 7 hours and five days were over 9 hours.
That's probably not good, and I should work on it.
And actually, these numbers don't even tell the whole story - a lot of those large numbers are a 7 hour sleep and a 4 hour nap later - it's just my sleep-per-day count.
This is one advantage of going through numbers slowly, by hand, instead of on a computer. If I saw 8.2 while skimming a spreadsheet, I'd say okay, that's pretty normal. Instead, I see my sleep is all over the place, and I think I should structure my day a little more systematically to smooth that out.
