self-analysis

Daytum, co-developed by Nicholas Felton of FELTRON fame, is a web application for collecting and communicating personal statistical data.

I've recently begun interacting with this application in hopes to make good on my claims to quality as a creative professional. Quantitative evidence is a compelling way to verify just how dedicated you are to developing skills, although it's easier to apply that principal to something like time spent with adobe CS software as opposed to time spent thinking critically. Self-documentation can be pretty tedious too, and I sometimes wonder if the time spent keeping track of how much I'm working isn't actually inhibiting me from working.

How much can you really tell about a person by their time investments? Is this quantitative method of presenting yourself overly reductive? Can you really put too much stock in numbers?
