To-do lists encourage 'I didn't finish' feeling at end of day. Done lists — what you actually accomplished — track real output and counter the perpetual undermining inner narrative.
How to track
End of each day, write 5-10 things you actually did. Include small wins (responded to that hard email, had productive conversation with X, completed report). Review weekly.
Most professionals accomplish more than they realise daily. The done list makes it visible. Improves both performance review preparation and daily mood.
