It is interesting that those who have urged the path of non-attachment have done so from the perspective of later life, having first experienced all the agonies and ecstasies that attachment can bring.
It seems to me that non-attachment is an aspect of wisdom that can only be achieved as part of the wisdom of aging.
Young people need to experience attachment, to ‘feel’ value through it and so gain an understanding of what is important and worthwhile. Without this understanding, there is only ‘detachment’, which negates value.
Non-attachment recognizes and acknowledges value but without the need to hold on to it, be it in the form of a relationship, an idea or experience or something material.
Only through holding on in the first place can you learn to let go . . .
