The power of a task management system like OmniFocus is that it allows you to filter your tasks instantly and show you only the things you should be thinking about right now. It frees up your brain to focus on what you’re doing instead of trying to keep track of all the loose ends that are hanging out there.
That’s the only thing your system needs to do. Free you up from wasting brain power remembering things.
I use a Bullet Journal, but I’ve got my daily routines in Things. It’s all about what works for a specific job.
If you’ve been wondering how to use OmniFocus this is a decent starting point.
