I agree with the idea that giving up is not always a bad thing.
Refusing to give up a bad habit can not be glorified simply because it has some element of presistence and endurance, qualities that have often been praised. A person adicted to a drug will really have to giveup the adiction. In such a case, giving up is the best course of action.
It will be counter productive to persist in a toxic relationship with an abusive mate because we don not want to be labelled a quitter. And as such, we endure mistreatment and abuse.
The act of giving up may come with a stigma to it, but often we need to give up. Give up a lifestyle, poor attitude towards work and others.
