Few days ago, I learned emacs org-mode for almost 10 hours straight. It was FUN. It felt like org-mode was loaded into my brain Matrix-style. I saw couple of videos, read through the manual and tried out my made-up examples. I read the manual cover-to-cover, metaphorically of course. If you are a more of a literal kind of person, I mean that I read the manual first-link to last-link. I skipped only the sections that described features that I thought I'll never use.
org-mode is beautiful. I had a lot of omfg moments. I believe it is going to have a significant positive impact on how I get and keep my ducks in a row. I won't go into the details here, but I'll just say why org-mode is better than all the other organize-your-stuff / project planning softwares out there: It is notes-centric rather than task-centric. Learn more if that makes you curious. Some people have learned Emacs just to be able to use org-mode, I hear!
I've become a fan of marathon learning sessions. There was a time when I prided my multi-tasking skills. I was just fooling myself. Interrupted time makes for pretty low quality time. I'd like to try this Quality Recluse Time type of effort on few other things I want to grok. 'Lisp Macros' is what comes to mind first. I've put off learning Lisp Macros for long enough, I suppose. I kind of know it but I want to learn it well. I mean, *really* learn it well. Ironically, that is how I've put it off for this long - I should just start.
