"Plan Project" would leave me with a blank. My tasks like this are more specific, but still without demanding a result, because if I demand a result I may freeze up. So my tasks might be like:
- Spend fifteen minutes brainstorming into a text file re Project.
- Spend half an hour reading Project documentation and taking notes.
- Spend twenty minutes talking to Joe about ideas for Project.
If I can't even get this specific, the task is:
- Write a task for planning Project.
