Totally agree with @wells.christopher on the fundamentals. I do wrist circles and finger pulls before fine work. Takes two minutes but stops cramps dead. My brush hand is so much steadier now, it's like night and day.

Ugh, my cheap backup light died too last week. Fumbling with my phone on a dark country road was a total joke.

My coworker Ben had a client meeting about a software update last week. They were all agreeing on a launch date and nodding along. His partner suddenly asked if "launch" meant a full public release or just a beta test. The room got quiet because nobody had actually defined that yet. That one question sorted out two months of work and stopped a big fight with the client. Now Ben makes everyone explain what they mean by simple words at the start of meetings.
