@humanearl maa darling, you are right about planning but then it's still very much HELPFUL.
Let's say one was to make over 100mistakes without planning in any thing but when planning was involved, it reduced it to 25mistakes. See! Also, it just reminds us that no matter how much one plans, error is bound to happen and that's because we are not perfect.
YOU ROCK!
I agree that planning helps to be prepared.
