While I most probably don't follow the tactics of GTD (haven't read them and don't want to) I aggressively follow a strategy that really works for me : reducing cognitive load. I make a point to commit nothing except the task on hand to my working memory.
When I say "I should remember to", I immediately stop and use a Messenger bot I coded for that purpose
When my wife say "Can you remember to" I immediately ask her to put it into our shared calendar, or I add it to the same bot
When a coworker says "can you do X", we add it as a trello card with the appropriate priority
People start to get used to it, they probably assume that I have very bad memory or that I'm weird, and we make it work :-) I feel very light since I started enforcing these procedures
I wondered the same thing. It shows up in Chromium but not Firefox. It is apprently character 0x14, or ASCII for "Device control 4". First time I come across this character !
One of the keys to GTD is capturing tasks, which is precisely what you describe. After they're captured, you can plan them. This is the second thing you describe (putting something on a calendar, or into a work queue like your trello card).
If you do that, you're already getting most of the benefits of GTD. Getting everything out of your head so you can remain focused on the immediate task at hand.
I'm a novice programmer and have been building my own small personal web app for remembering references[0]. I'd love to take a look and learn from your bot if you're able to share the code!
The bot is freely usable at https://www.facebook.com/botremindme (it also had a landing page, but, smart me, I did not renew the domain and now it's squatted by a porn site).
I need to take an hour to open source the code, that's clear. But feel free to try and let me know if you have any question!
