Keep the things you've recently accomplished at the top of your mind, and you might boost your momentum and productivity. That's how Lyndi Thompson, a demand marketer at Tableau, organises her Trello board. The board is also structured for an agile workflow, with lists that track current tasks and "next up".
You can use this template if you're a Trello user or just apply the "done first" strategy with whatever list tool you use. The list can also help as a reference for quarterly or yearly retrospectives.
In any case, a "done" list can be very motivating, so remember to start your day reviewing and tracking those completed tasks.
