Doing things for other is also activities, and you also seem to be focused on what you get (sympathetic joy) from that.
You are right in that doing the same things for literally decades can get boring. Rethinking your life and trying different things is part of aging (including focusing on yourself, if what you did all your life was to do stuff for others)
It doesn’t bother me at all, unless the person tries to also say that selfishness and selfish motivations are to be avoided.
Try to find a way to embrace and appreciate your self-interest. Humans are not evil just because of their egoism, and nothing about egoism is inherently evil.
Or do you mean pride?
One cannot be charitable if one does not know his or her own defects and virtues. And this is a lifelong exercise.
Trivial? Would you expand on this? Any examples? Thank you.
