Weekly planning is an important process during which you give your week a focus. During this process, you ensure that you work on tasks that help you accomplish your goals, your projects are on a right trajectory to be completed and that the tasks that have to recur, recur as frequently as necessary.
If you have tasks related to a project and they have to be done at the specific time, move this task to your task manager. Don’t move conditional tasks to your todo list, they should stay in a project.
