Agreed. There’s plenty of suffering that happens in life just because. Purposeful suffering doesn’t seem like a good thing in most cases.
But there’s also the issue of the definition of suffering. Minor suffering like tolerating a colder thermostat setting in the winter, it saves money and energy, seems rather subjective on where the line could be drawn on bad vs good.
Not strictly about boundaries, but I think you’d like the Evolving Self by Mihaly Csikszentmihalyi. It goes a lot into how to consider your priorities in life and what you want to spend your time on
