Would love to hear more on this... Doing a "time audit" for a week has been on my list for a while and I've just avoided it.
Is an old school pen and paper carried with me and a timer the way to go?
I use a 15-day cycle called
self-sprint (don't bother googling it, it's not on the web).
What it means is every 15-days I take everything related to work and plan ahead using a google drive excel spreadsheet, and focus on one major goal I want to achieve.
To do it I first create a
backlog where I write down every activity I need to do.
(including fun time, friends, reading, studying, workouts, family, women, etc)
Then I assign blocks of time to do those activities, prioritizing them by order of importance.
If I take more time than what I slotted to complete it, I write it down. The same if I take less.
All activities that are not completed go into their own columns were I either postpone, or reassign them for later.
I also write down ALL interruptions, and the block of time I had to use to take care of them.
At the end of the cycle I start over, carrying over the activities I haven't finished and merging them with the new activities that pop up for a fresh 15-day cycle. Then I look back and access my overall productivity (hours worked vs tasks completed).
It's the best system I've ever followed and you can use mostly any virtual tool with it (like trello, asana, etc).
It also boosts your productivity while decreasing the amount of time you need to work.
