Having a clear structure to work in is completely different from making plans about something. If you make a plan, you impose a structure on yourself; it makes you inflexible. To keep going according to plan, you have to push yourself and employ willpower.
Frameworks for how to work can be freeing and helpful. With no next actions, I easily forget ideas. With a workflow to read, process, process, write, I don’t need to store my next actions in my head or left to highlights.
