Beginner for 5 years anxious confused

What I did: BEGAN MOSTLY NOTES

What happened: SEEMS LIKE THEY JUST PILE UP

What I expected:SOME MATRIX OR SOME FILE SYSTEM

Things that might be helpful to know (Agenda version, OS and model, etc):

LATEST MODEL I am just expressing my desire, longstanding, to use Agenda as my basic planning and scheduling tool, and my desire to journal a bit in it, and maybe link my novel and textbook writings so i can use this agenda as a hub. However, i am just feeling for years stupid and not getting traction I will have to admit i am sure this app is great for a lot of this, so why is it not just unfolding as i use it duh. ???

Just organize stuff by areas of your life and related “projects” (which can be a file system). Use hashtags, use dates; there are so many ways to get organized
