I have a marker board in my office and can't sit at my computer without seeing it (it's behind the monitor).

I typically write out 2-3 goals on it for that day.

Often, they include a percentage completion of whatever I'm working on, be it Medium/Client work:

1. 100% (write the entire article)

2. 25% (start one)

3. Draft 10 ideas

I also am forgiving of myself if one goal isn't working out, so long as I pivot and adapt another productivity milestone in its place.
