in a way yes, but in a way also no, because in real life you can course-correct. I.e. you don't just have the initial shot, you also have the ability to make decisions along the way
True, but plans change everything.
Once you complete a plan its more than just a plan, its a step i different direction.
If a plan has any substance it changes the game.
So if a plan happens sometimes completing a plan makes the game different.
In snooker this means the ball move in some predictable direction, but in real life some plans are clear cut and either 0 or 1. Some can have multiple meaning depending how many side quests you do.
Most people plan to achieve clear objectives. Like money, or social stuff.
Those objectives can be achieved in multitude of ways of course.
Some ways are more obvious than others.
