I am new to GTD and have been monitoring this forum for sometime. While I am in the technology industry and behind a computer all day long at work, at this point, I find myself more comfortable with index cards while I organize and tweak my system. If I ever get it under control and designed the way I want it, I'll look back to developing it in some electronic format.
I previously managed my NA list in excel and was able to quickly filter my NA list by context, and or associated project. Initially, the list had become exceptionally long and I became overwhelmed by it and lost control over it.
I've seen the articles on cascading next actions and pigpog, or single items per index card, but have any of you found a good way to manage a voluminous list of next actions with index cards? TIA
