Nope. Doesn’t help. “Live the example” only works for the person living the example. Does nothing whatsoever to change the person you believe needs to change.

My solution: if there are people that I believe need to change, and they do not, they exit my life. If I cannot make them exit, I minimize them. There are too many people in the world who, as they are, I find perfectly acceptable for me to waste my time trying to transform someone who is NOT acceptable to me as they are into someone acceptable to me. Attempting to transform that person only makes that person AND myself less happy.
