I wouldn't title them as already performed—that seems to take away my enjoyment of the present moment... cheating me out of enjoying the "work" and the incomplete state of it. Like living a memory rather than life itself....

Anyway, it might be helpful to name it something that reflects the central goal(s) of the project, to help you focus on the essentials & not let the project morph into something else along the way.

Examples of what I mean:

Buy tires for car vs. Buy safest tires for car
Buy catfood vs. Buy cheapest catfood
Correct proposal vs. Make proposal sound professional
Take a balloon ride vs. Take a balloon ride over stunning scenery

Not that every project needs this elaboration, but it might help to maintain focus for some projects, especially those that are more open-ended or that are on your slate for a long time, and it'll never hurt to think first about the goals you want each project to meet.
