This is a, indeed, a very powerful opinion. Especially because most women I know, my mother included, think they have to ‘dedicate’ their lives to their children, sometimes at the cost of what they want or like or even need.
I completely disagree. Mothers would be more valued in a family if they were happy doing what they were doing, rather than doing everything for the family, but resenting the family as a result.
I know keeping my mother calm and happy ensures we all remain talking and chilled at home. The day she is upset with anyone of us, the others suffer too.
And no, I do not think being a mother is necessary to know that being a mother should be one of roles and not the only role you play.
