How do beginners keep track of their trades before they have a journal habit?

A full trading journal is the goal, but most beginners start with something much smaller — a spreadsheet, a notes app, screenshots, or nothing at all.

What did you start with?

• how you recorded your first trades
• what you looked back at most often
• the moment you realised the records mattered
