Using an engineering notebook

Keeping a physical engineering notebook—writing detailed, dated, real-time notes by hand—can significantly improve productivity and thinking clarity. The practice involves recording work as it happens with enough detail for someone else to replicate, creating a permanent append-only record. Writing by hand aids memory retention and forces clearer thinking before coding. While only 25% of developers use this practice, it's worth experimenting with different formats and detail levels to see if it works for you.
