Guess I'll throw my two cents in here as well.
It's so important to be organized. And not just notes on a yellow sticky organized, but ORGANIZED.
I have 2 binders I carry around with me when I travel, go home, at the office, where ever. One binder has all my data. Every object on my mush is in an excel spreadsheet, with description and location. Any objects connected to that object (db's for example) then branch down from there. I have a spreadsheet with all my planets, ships and HSpace coordinates. Because I have 2 other DBs from 2 other games I grab code or inspiration from, I also keep identical spreadsheets of their vnums for reference.
I then have spreadsheets for my factions, commercial businesses and black market/VIS. My chargen has a section, as does any third party soft code I have (volunds, Dahans etc). I also have a huge section on Rhost, which is basically some charts showing different functions between the two and pages and pages of conversations with @Ashen-Shugar
My other binder is data. Because I'm doing a Star Wars themed D6 game, I have 4 rule books and 4 add ons of WEG D6. I then have every dictionary, picture book, reference manual, visual dictionary possible relating to Star Wars and TFA series. This binder is big, almost 600 pages. It's all tabbed, so if I want to know if a certain planet is canon and what species are on that planet and where it is in the galaxy compared to Tatooine, it takes me maybe 30 seconds to look it up, no matter where I'm at.
I then have a 3rd smaller binder that has my website / tech stuff. Server stuff, and everything from my WIKI database spreadsheet to the web fonts I want to use to the bootstrap / css manual.
In my office I have 4 whiteboards that I use constantly to brainstorm, 3 monitors and 2 computers.
My todo list always sits front and Center, and being organized allows you to spend time coding or writing or building instead of scrambling around looking for something. It takes a long time to gather your materials and organize them in such a fashion, but imho it is worth it in the end.
Cheers
