I have a category with everything I intend to do to the child if I have kids. I have a category with pictures of me every year from 3 days old to today. I do the same with my parents and grandparents (which is more spotty).
I have a category on all the friends I've ever had, what they liked, why they liked me, what I did to become aquainted, birthdays, their parents, all the information about them you would expect a close friend to have.
I've got all my tax returns back to 2005 (I started the wiki somewhere in 2007). My current net worth plotted on a chart, documented by what I did which caused certain plunges and rises in that graph.
A big category on girlfriends, kinds of women and what works with some. I can give you a cruise through every significant romantic event in my life from my first kiss back in college to sexual encounters. With photos of each girl. Each girl I dated given a full psycho analysis, funny how I searched out each edge of the (Smart, Sane, Pretty pick any two) triangle. I even dated a few (1 of 3) and (0 of 3). Big mistakes that haunt you.
I have a category of books I've read, and plotted those against my life timeline. What I've thought of them, how they changed me.
Anyone who got ahold of this wikipedia and had 20 hours to read it all would know as much about me as I know about me.
This wikipedia is what I want to see on dating websites, If I could include this on a dating website, and have all the girls do the same, it would make dating a lot easier. I imagine a post with dental records, tax returns, employment, income histories, aspirations, books read, history of diseases/conditions, family genetic lines, computers owned, friend structures, self psychoanalysis, and hundreds of other subjects which makes us unique from other humans.
A big worry is that the hard drive bricks iself or gets stolen, this wikipedia is worth tens of thousands of dollars to me. My backup strategy is to make a hard drive cloned image every 3 months with clonezilla, with the hd stored in a physically different location. so my wiki would even survive an fbi takedown where they steal all your stuff.
I've got all the programs I've ever written saved, so I can go back in time 4 years and see programs I wrote in C++, Visual Basic. It's like reviewing your essays from first grade, I can't bear to see them, my programming skill has gone up slowly but surly over time.
The real secret is adhering to the rules of a wikipedia. Nothing may be added without establishing its link and relevancy to another page. Also, Here is the secret sauce, a tough rule is that when you introduce a new page that links to an old subject, which introduces new information, or new evidence which contradicts old pages, you have to spend time and re-build the pages being linked to. I have a system where editing one significant page has the possibility of having me go back and change previous observations, the benefit is that it automates your thinking process. If you keep all your thoughts you ever have into a tight tree form, you can find that your human memory is upgraded a hundred times over. I was able to use process of elimination to determine which foods were causing my acne, and through continued graphing and elimination, was able to find what elements in which foods were causing it. Something many doctors would probably like to see. When I go to a new dentist, I sometimes bring along my entire history of each tooth, each operation i've had, i can see where that time I kissed the wrong girl caused a microbe party in my mouth which caused cavities. Though the dentists have no idea what microbes are in my mouth, through my wiki. I have a good idea. In some ways the wiki makes me a better dentist (to myself) than the professionals.
It's a wikipedia that treats myself like scientists would treat a newly discovered intelligent alien craft. Everything about it is described, graphed, analyzed, compared, and charted. Nothing about it is taken as a given. The part that keeps me coming back to it is my thirst for knowledge. When I browse hacker news, stackoverflow, and (years ago, digg), anything that struck me as useful for growing myself or growing knowledge was included. So now I have like 800 items in a list organized by category and awesomeness, that to this day when I look at it, I still see the importance. I have a category of guitar songs I can play, piano tunes, how I learned. etc.
Whenever I hear a song that provides a certain response, sadness, happiness, euphoria, depression. I write it down on a receipt, then when I get home I log it. So I have a series of songs I can play which seriously induce all these emotions. I try to stick to the happiness songs. there is a boat load of ones that cause the other emotions. As a result I have 30 songs that when I play, suddenly make me happier. Sometimes when I'm depressed I play the depression inducing songs and it makes me extremely depressed, and I can look at myself like a computer, an input output device, and I see that depression is only a response to external stimuli, if you can take control of your external environment, you can custom make your emotion for that hour/day.
