I noticed a lot of time dissapeared on unimportant things, and my productivity and motivation was inconsistent. Some days I would feel motivated and get a lot done, other days Id languish and could not really recall what I spent time on or what goals had been achieved.

I looked for a good app, but the note takers were too general, and a spreadsheet was not easy to use on mobile, many time tracker systems were slow or overkill. Eventually I started working on a simple web app to do this. I added an automated timer clock, and this at least allowed me to note down tasks. I started off writing readable sentence notes, but migrated to a terse form with just keywords. I added a simple filter search and found that worked well : I could zoom into areas of interest by keyword, such as shopping or weight or fee or run or billable.

I gradually noticed a useful psychological side-effect of tracking my time : I wanted to get stuff done just so that I could note it down! Id catch myself thinking.. Hmm I havent put in any entries for exercise the last 2 days, I better do some situps or a run so I can put that in.
So actually noting things down had the effect of pushing me to get more good things done.
Theres a kind of objectivity, and also the effect of your motivated self observing your unmotivated self and kind of comparing the two.

I recently heard a talk by memory expert Josh Foer, about autopilot subconscious plateaus. This is where your activity matches your expectation set point at the OK level and so your conscious mind doesnt need to be engaged. We do this everyday for routine tasks, we perform them uncounsciously or rather subconsciously, on auto-pilot.

Autopilot is great for things we dont want to improve : washing dishes, shaving, driving to work.
For things we do want to improve, we need some way of making the activity stand out to our conscious minds so we can evaluate performance and goals and try a different strategy. Time tracking seems to help with this, it makes you review what youve just been doing.

Im not recommending tracking everything, in fact I think its good to decide to not track some areas, maybe the weekends or reading time in the evening. But it can give real insight and motivation for those areas we want to improve : lose weight, gain fitness, reduce cigarettes, study more effectively etc.
