Vietnamese women's football has had many years of stability, even brilliance. A generation of players attached, a familiar coaching staff, and a way of operating that has proven effective over many years. Success, from a certain perspective, is something that easily creates a sense of security illusion, so that people believe that keeping it still will be okay. But reality shows the opposite, to request a shift, it must start as soon as it is still at its peak.
Therefore, the transfer is not discussed in the "should or should not" aspect, but like a tree having to change its leaves in season. For collectives and organizations, it is the perspective of when and how to transfer.
Too early, accumulated values are difficult to maximize. Too late, the future will be affected. In football, sometimes people wait until the results go down to change. But then, change is no longer proactive, but a reaction. It's like treating a disease when it's severe, instead of taking care of it when it's healthy.
In work, many people are attached to a position for too long to the point of forgetting what they need to learn more. In a relationship, some people keep it by habit, not by common development. In the family, there are ways of teaching children that are repeated from generation to generation, even though the context has changed.
Everyone has a common point, knowing that sooner or later they will have to change, but because "it's not time yet", they just leave it there, as a clever way of delaying.
Therefore, you must think of transfer as an obvious and not scary thing. What is scary is seeing but not being prepared. When the consequences occur, you call it a fluctuation but it is actually just the result of what has accumulated before.
Of course, not all changes lead to progress, but if there is no change, it will almost certainly be left behind.
When you accept "the obvious", you will have enough calmness to recognize the time to prepare for the transition and enough courage to start.
