Right, well tasks and achievements might require patience but also, time limits must be taken into account. To use the example of preparing food, lets say you're running a restaurant where you're preparing food for customers. When you're preparing meals you of course can't rush through it and thus make meals that aren't as good and that customers wont enjoy, but you also can't take too long to make the meals because your patrons don't want to wait too long for their food. Especially at restaurants where you're seated, not at fast food places, most people are aware that they do have to wait a bit for their meals but by the same token, they don't want to wait till next Christmas before they do get their meals. Also, if you are able to produce meals as quickly as possible while still retaining all their quality, that way you will be able to serve people the fastest and thus have the most tables available and be able to serve the most people and make the most business.
