@mediapathic Thanks for sharing! Without some good ideas it’s quite overwhelming if you have to start on a clean state and really don’t know how to begin.
@RikD Thanks for the info on how you work. I found the drops/clouds/concepts/models structuring very interesting and logical for me. The image also helped a lot!
Both: Your explanations gave me some more insight. I’ll now start collecting (atomic) notes, settle for IMF and see what comes out of it. 
Anyone got a good suggestion for bilingual people? I’m half Brit, half German, and recognise that I constantly write (and think) in both languages, sometimes even within the same note.
This of course leads to all kinds of mixtures, searching problems and different tags. My everyday communication and work is about 50:50, so I can’t really decide on one language—and I’m too lazy to translate everything.
How do others handle this?
