Ten Excuses For Not Planning

Our jobs are different. It is very dynamic, so it is not possible to plan and progress according to the plan. No need to waste time planning.
It is not clear when and what MS Project will do. (I don't know how to use MS Project correctly)
Our resources are always limited. (How to plan resources, I don't know)
The critical path in our project is very variable. (I don't know what the Critical Path is)
The customer's requests for changes disrupt our plan. (How to do Scope Management, I don't know)
Financial needs do not match the incoming monetary resource. (I do not know how to determine the budget)
The scope has expanded gradually, but senior management wants the project in the same budget and the same time. (The quality of the project is ignored)
I spend most of my day creating reports to senior management. I cannot find the opportunity to plan while writing a report.
I am not able to manage the project activities as I cannot get the necessary support from the department managers.
We know the subject of project management, we do the planning from our mind.
