Write it down to think

Writing is the cheapest tool a working professional has and one of the least used. Most ideas are clearer or worse than they seemed in your head, and writing reveals which.

It is also the first form of operations. Anything worth doing repeatedly is worth writing down, because writing is how the work survives you being tired, sick, or absent.

A short paragraph at the end of a project is one of the highest-return time investments available in any trade. It costs ten minutes and saves the next person ten hours.

The notebook habit is unglamorous and quietly career-defining.
