The concept of a 'second brain' to store thoughts, ideas, and tasks is popular with apps like Notion, Evernote, and Obsidian, but the focus should be on generating output rather than just storing information.
Taking notes is easy, but creating something by organizing and expressing what is learned is more challenging yet productive.
Instead of just storing information, the emphasis should be on creating and sharing one's work to make an impact.
The key to completing a project is to 'go public' by sharing it with others, encouraging feedback, collaboration, and the potential for unexpected successes.
