I'm glad people cared enough to spend their important time on me and help me along in my journey.
If we derive pleasure in being "right" and showing how other people are "wrong" then we may not have the best intentions which can certainly impact the outcome. If instead we work to help people become the best version of themselves which may include shedding some limiting beliefs, that could be a very good thing for everyone, including our existence on this planet.
I'm glad to know that you have had others there for you. It tends to make the journey of life less burdensome. Yes, being "right" is vain, and some of us have had to learn that through some humiliating circumstances. And yes, shedding limiting beliefs is definitely a plus. And while it is a virtue to help others become their best, there is a time when that work is to step aside, and let people reap what they have sown.
