About 5 years ago I read 'Getting Things Done' and (despite my misgivings) it literally changed my life.
Since then I've:
- set up a JIRA to track ALL the things I work on
- written a book https://www.amazon.com/Docker-Practice-Ian-Miell/dp/16172927... (and am currently writing a second edition)
- started a blog https://zwischenzugs.wordpress.com/
- changed jobs
- become a speaker https://www.youtube.com/results?search_query=ian+miell
- started an open source project that helps me automation my spare time tech work: http://ianmiell.github.io/shutit/
And now I feel I've got MORE time than I had before I read it, and better time with kids etc..
The takeaway from this is that if you get serious about managing your time the benefits can be awesome.
Although when your kids are very young (we had two demanding ones under 2) don't be too hard on yourself - it's really hard!
Just came here to say that time management is key. When we had our first child, I learned this sink-or-swim style and it made me a much better human being because of it.
