For me the most notable one is the adoption of a GTD system for task tracking, which I did in concert with two related changes: starting inbox zero, and switching from bookmarking-and-categorizing to clipping-for-search reference material. I started each of these around 9 years ago now, and can't imagine going back. The greatest impact isn't even literally on "getting things done", but on the time when I'm not working. I don't have to hold things in my brain. When I'm not working, I can forget about all that stuff and actually rest, or focus on other things. And when it is time to work, it's all right there. (And by work, I don't just mean the 9-5, but essentially anything that needs to get done, vs recreation. Although I do also use it to remember things I'd like to do someday for fun—everything from books I'd like to read and movies I'd like to watch to things like taking golf lessons, or buying a new helmet.) We also of course use project tracking software for work, but I find it extremely beneficial to have my own personal system as well. Everything goes in there, from large, ongoing projects to 'remember to switch the laundry over'. I wrote a blog post a few years back describing what works for me[1]. For the most part it still applies. I use Evernote, but would probably look at something like Joplin if I were setting it up today. (And will probably migrate, someday.) About the only other significant difference is I do a lot less sending emails to evernote now, since the gmail 'snooze' feature is pretty convenient. I'll still do it in cases where I want to add some notes though. One thing to be aware of is if you're used to a less structured system (a written agenda, sticky notes, marked-unread emails, etc.) this will take significant time to adapt to. It was my primary focus for the better part of a month just to get things set up in a way that felt good to me, and then another couple of months before it stopped feeling like extra work to make myself use the system. But in the years since then, I can't imagine having lived without it. (And I built a fairly successful company and had kids over that period.)
