To Plan to Plan

I am so terrible at planning. I am constantly getting ideas. Ideas for games to build, books to write, software to build, things to make. I am very much driven by inspiration, usually to my own detriment.
I get an idea and it consumes me. I must make it real. So I dive in and start coding etc. I know that there will be other all-consuming ideas coming up so I have to get this one done while I'm still excited about it.

But then the complexity grows too large for me to visualize it and it fizzles out. Some form of planning or visualization is a necessity. The IF game I'm building to demonstrate my text game engine is a great example. I just dove in making a space game where you escape the brig and explore the ship, encountering all kinds of interesting things.
But now the game is large enough that I can't visualize what I've already built, what is remaining, where rooms are in relation to others, where I hid puzzle pieces etc. Sure I left myself notes but yyeah.

I should have at least been planning as I go. In this case planning can be as simple as drawing a blueprint of the ship and making notes there. So that's what I started doing last night. I'll work through each of the rooms I've defined and build the blueprints.
I'll also be improving the tools in my game engine for mapping out what you've coded - this is challenging in a console environment.

Next time I plan on planning.
