Zettelkasten, Second Brain, and Digital Garden Serve Different Purposes

The Second Brain is for:

• Organizing the incoming information
• Moving your projects forward

Zettelkasten is for:

• Connecting your ideas and gaining insights

Journaling (aka Daily Notes) is for:

• Emptying your brain for new ideas
• Mental health overall

Evergreen Notes are for:

• Refining your knowledge

Digital Garden is for:

• Sharing your knowledge

Thus, all these methods do not contradict each other, but rather complement each other.

However, you probably don’t need all these things at once.
