For personal learning: I use a personal wiki and update it ASAP whenever I learn something new, be it via a meeting, reference, news story, link. A collage of references. I use pmwiki but the wiki always-editable concept is more important than the software.

For meeting that are more formal/have deliverables, these are always minuted and shared. It's surprising walking away from a meeting with a seemingly clear conclusion the interpretation others can have several weeks later unless this is done. Stay on one page, literally. This could range from a photo of the agenda and notes made with highlights, to typed, depending on what's allowed/information security policy.

For notebook, I have a bull clip with loose paper which may include blank paper, templates, etc. When something's not needed, I shred it.
