It started with to-do lists and New Year’s resolutions (that I never kept), but I quickly realised that I needed a more elaborate framework that allowed me to track important data without spending too much time on its maintenance and analysis.

Over the years, I researched, tested, modified, adopted and discarded dozens of techniques. Some required too much commitment, others didn’t provide enough data for meaningful insights and some just didn’t fit into my routine.

In addition to finding the optimum framework, I had to decide what data to gather, how often and in what format, all of which took a lot of trial and error. It’s still a work in progress, and maintaining and improving the tools that help you optimise your life is a part of the optimisation process.

Here are five techniques that served me well over the years. I hope you find them useful too!

At the end of each month, I rate my perceived satisfaction with the following eight areas of life on a scale from 1 to 10:

  4. Home
  5. Health and fitness

Of course, this doesn’t tell me what went right or wrong, but looking at a heat map (I view this data in different formats, but a heat map is the default) at the end of the year, I get a bird’s-eye view of what went well and what needs improving. It takes less than five minutes at the end of each month and serves as a prompt to review and reflect on the personal goals, achievements and areas of…
