On my work machine I’ve installed RescueTime. This tool monitors the processes and websites. Everything is categorised and a weekly report is sent to my inbox.
Last week I noticed a RescueTime Channel on IFTTT. A simple receipt logs my daily report to Evernote. Now I know what days I perform best.
“When you can measure what you are speaking about, and express it in numbers, you know something about it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarely, in your thoughts advanced to the stage of science.”
― William Thomson, 1st Baron Kelvin
