Planning is really a rough sketch of how you want things organized and how you wish them to go. The rest of the time you should be chipping away at your goal.
Plans jumpstart the action engine just like stretching warms you up to exercise.
Plans never pan out exactly how they were designed. They often get tweaked along the way. Flexible plans enable more opportunity while rigid plans impede pivoting.
Planning sets the general guidelines for execution. Move forward and adapt.
