Start with one dedicated notebook. On the first page, draw a simple title:
Mind Garden
A place to plant thoughts, prune ideas, and grow clarity.
Then create a Table of Contents for the garden sections.
Since your digital version has Do / Decide / Delegate / Completed, you can recreate this easily.
Next to any item draw a small symbol:
● = Do
◇ = Decide
→ = Delegate
✓ = Completed
Example:
● call Sarah
◇ choose workshop topic
✓ planted chamomile
Each list becomes its own garden bed: a section of the notebook.
