I've been writing down notes, thoughts, ideas, concepts anything at all that seems remotely worth keeping at the time and I used to hit this particular bit all the time:
> I do less well at capturing the level of detail that made the idea exciting at the time.
Thoughts and ideas usually require context to frame them in the way that is exciting. When writing down notes I always have that required context in my head but I didn't capture that as well. I still start by writing down the part that I'm excited about but now I spend some time trying to capture that context.
What was I reading, watching, listening to when the idea occurred. Where was I when it occurred? Was there another thing I was trying to work through that led me to this? Do I have notes on that other thing, or any other related topics? I was thinking about that I can connect this note to? Coming to this thought cold is there some context I need?
The problem that I mostly have now is that my collection of notes is quite vast at this point and of varying level of quality and detail. I occasionally will spend time pruning, refining, and cleaning up my notes but I tend to produce more than I consume. I've started to focus on places in my notes where there are a lot of tight connections between notes. It means its a place that my mind keeps wandering to and where I have a high density of ideas.
I'm still looking for better ways to manage and refine my notes so these threads are all very interesting to me hahah.
