My notes track knowledge, they are referenced as-needed so I store everything because there's low/no cost. I've also found that writing things down improves my recollection, so there's value even if I never reference the note again.
My calendar / omnifocus track future actions, I minimize these and keep them very well curated - no "todo", only "do". Externalizing some cognition takes time in exchange for efficiency... less overhead from context switching or remembering unrelated items.
The tradeoff is loosely analogous to scheduling in computing - inefficient for an isolated single thread of work, but beneficial when coordinating lots of concurrent work.
I'm curious about what this means. What are "do" notes (as distinct from "todo" ones). If it means that don't calendar, and you just do that task immediately, how you plan and (more importantly) remember future tasks?
Grep any large code repository for "TODO" comments.
However, I think code and life are slightly different contexts here. I get what you mean about separating aspirations from near-term actual intents but I generally use the word "todo" to refer exclusively to the latter (which still doesn't help a whole lot with ensuring execution as the list still grows quite large).
I keep the two separate: good notes describing the state of the world, and a calendar to schedule future actions.
When it comes to software, that means all code must have good documentation and known flaws are scheduled to be fixed. If it's not worth scheduling, it's not worth changing.
My personal life follows the same pattern, although much less formal... there just isn't enough time for every possibility, so I always work backwards from my calendar.
I have system of using "top" tags to define my working view for a project. Say I'm working on project Foo. At any one time I'll have about half a dozen notes tagged "foo-top." I can take any note from my past and bring it front and center by tagging it "foo-top" and then delete the tag when I want the note to disappear again. Say, for example, I want to see if CouchDB will be useful for Foo. I used CouchDB for a personal project several years ago, so I can search for my note of CouchDB concepts and commands, tag it "foo-top", and then remove the tag if I decide it won't be useful. It's a beautiful way of carrying around a lot of baggage without feeling the weight. It's nice that if I want, I can write down notes and thoughts about something without worrying that I'll clutter up my journal and make it unreadable, or worrying that I'm mixing up the wheat and the chaff. It's not like I spend a bunch of time rummaging through a bunch of junk to find what I want, forcing me to think carefully about what I record. I can record anything that seems like it might be useful later.
A journal would be nice to have, too, though. One note in each project serves as a journal of sorts, in the form of a quick summary of what I've done each day and a quick summary of what I expect to accomplish next. (For work, I find it more convenient to keep a single note for this instead of breaking it out by project.) Evernote isn't great for keeping chronological notes. I only use it because I haven't seen an alternative that is compelling enough to make up for the convenience of using just one program.
One thing I really wish for is a program that could automatically present me with a diary of sorts based on my note-taking. Versioning would be nice, too, so I could see how my notes evolve over time.
Is there not an API in Evernote to query the notes? Seems like getting the last few weeks’ worth, sorting, and dumping to html or pdf would go pretty far for your diary use case.
I read my notes every now and then. But what the notebook does mostly is make me focus and concentrate on my goals and remind me what's important. As the parent said, a notebook enhances your long term memory. You re-iterate lessons learned/forgotten. It's not a bookmarking tool.
The importance of the 'reset' has helped me a lot too, and calling a lot of recorded things 'baggage' is very true. If everything I had recorded was wiped would I be disappointed? Definitely! But life would go on. :) I'd re-discover things, my tastes and personality would change so those recorded things aren't relevant, etc.
I've mentored enough colleagues that I've come across those who take extremely detailed notes, and are successful, and a fair number who do this and don't find success in their work. When I try to find ways to get them to question their approach they are often resistant to changing because the have an ingrained belief that detailed note-taking is of fundamental importance.
Which makes me think there is something not so obvious that accompanies effective note taking.
Taking notes about routine everyday stuff is boring and worse than useless, because the notes are full of duplicated information that makes searching slower. I imagine the people who take notes for it's own sake are basically listing everything that they do, whether they gained any new insight or not.
I spent my entire education and most of my software career taking few notes, and they did the job well enough. Despite my shift to taking a lot more for various reasons, I agree that there is no moral or strategic value to taking nice notes just for the sake of having done so.
As part of treating my notes as a code project, I even keep them version controlled, which leaves me a little more free to just delete things or "refactor" stuff. A lot of the value I get is going back through things and synthesizing them into clearer and more useful notes. TODOs in particular are dangerous -- I try to treat files of that nature as extensions of my long term memory, rather than a curriculum which I feel obligated to follow.
That being said, there is an element of this project where I feel like a am building a piece of "my life's work". I've built a number of software projects, and part of building them over time and organizing them leaves them in a state where I am proud to have built them -- I can point out a piece of the system, and understand why it works that way, and remember the choices that led to its current state. At one point, I realized that I had no such project for my life, and it was a little weird that I had so clearly documented software systems that were hardly used, whereas my life and action and ideas and knowledge were, for the most part, just in my head. So in a way it's more than the practicality of having notes, although in the practice of it I have found it to be practical. It's a way of adding meaning to the course of my life -- now the ten minutes I spent reading an article can also become a gift to my future self due to the one choice quote I grab from it.
