I was going to make same comment… if you are watching productivity videos and trying out a ton of tools, that may be “Productivity porn”, but if you are over engineering you own PKM that may be the M-word! (I think the word “self-“ was redundant!
In all seriousness, everyone suffers from Procrastination and it comes in many forms. These tools and systems are a way to keep us focused, so it is valuable to watch what you are doing.
I think Markdown is a step forward for me — i to minimal formatting, mostly headings and indented bullet lists and a little bold if I remember. Simple is good.
I tag tasks that I know I am procrastinating on with how many minutes it will take, like #5min or i might use a tag of #avoiding.
Usually behind procrastination is some fear - fear of being wrong, of being judged, of being not good enough. Try to label your procrastination for what it is. But don’t make it good or bad, it just is.
It could be you didn’t get enough sleep, ate junkie food, had too many pints with the lads the night before. It could be the task is not even valuable.
Define a basic system and stick with it. Periodically, not continuously, make a deliberate change to the system.
I hope some of these things helped, it is simply what helped for me.
