How do you capture ideas/tasks that hit you while walking or away from your journal?

I’m hoping some of you have solved this because it’s been driving me crazy.

My brain tends to give me my best ideas and reminders when I’m walking, exercising, cooking, or commuting - basically anytime I don’t have my journal with me.

I end up:

- putting quick thoughts into the Notes app,

- recording tiny voice notes,

- or telling myself “I’ll jot this down later” (which… rarely happens).

But then those thoughts never make it into my BuJo system, so things get scattered.

For those who rely on your bullet journal as your main organizational system:

How do you capture “in the moment” thoughts when you’re not near your journal?

• Do you carry a small pocket notebook?
• Use your phone as a temporary inbox?
• Voice memos? Something else?

Would love to hear what’s worked for you.
