Planning big

To plan big you have to complete your own story, where you are the protagonist and plan ahead to achieve that. With that story in mind, schedule your calendar with activities, microgoals to achieve the change you’re seeking.
Plan something big enough and focus relentlessly on it. If you do several activities at the same time you’ll get nothing doneā€”at least nothing worth doing.
What if you stop whatever you’re doing for a moment and consider the point?
How big can you think? Is it practical? Can you decompose it in your calendar?
Doesn’t it worth the try? Then plan it.
