Some thoughts prompted by @pluralistic today:
During the past couple years, a change in my role at work created the need for me to be significantly more organized. I sometimes wonder if people think I have a good memory. I actually tend forget things within a day but I have adopted processes that prompt me to address outstanding issues at the appropriate time.
One mistake I made when first attempting to be more organized was trying to follow "best practices". My most valuable processes were not recommended by anyone. I experimented with ideas and found what works for me.
One area of organization that has significantly improved my life is budgeting. I have never found a budgeting program that has all the features I want, but I have found a flow with Actual Budget that has decreased my and my wife's finance-related stress by ~90%.
In my experience, commercial SaaS productivity tools are a waste of money. In their effort to appeal to the lowest common denominator, they often make it difficult to find a way to use the software that works for me. Simple versatile tools combined with personally-enforced habits work best for me. Automation is often overrated.
