“Planning is bringing the future into the present so that you can do something about it now.”
The key here is that you must have put in the time, effort, and energy into thinking about the future you want to create. So often people seem to simply exist through life or react to the world around them and then they get frustrated that their “plans“ haven’t come true.
You don’t really have a plan if you haven’t defined what you want the future to look like. You just have activities. You have energy expended with no defined return…
Define the future you want to create. Plan your work. Work your plan.
