A while ago I came across some questions to consider everytime that I do a review of my tasks. The problem is that I've attached the questions to a task in OmniFocus and -honestly- I don't think it's helpful to do something like that unless I think and write about it.
Is this system trustworthy? If not, why not? Do I need to make better backups?
No, there are two major problems with the personal productivity. The first is that I don't schedule enough time for something. How can I finish a task when I don't make any time for it. Secondly, I don't do enough positive reviews. I need to do a review every day to make sure that tasks don't fall through the cracks and I don't overwhelm myself. I find most of my reviews are when I'm under the gun. Not a good thing.
Is there a next actionable task? Can it actually be readily done?
Yes... for the most part. I have a couple projects that have items like "Brainstorm next action".
When do I anticipate looking at this next action’s context?
This goes back to the first question.
What will this project look like when it is done? Depends on the project, baby.
When do I think I’ll need to see this project again?
That also depends on the project.
