Almost every one of the people I’ve learned the most valuable things from were people that I did not agree with on other things. They were often people I wouldn’t want to spend any time around. Often people whose personalities irked me.
Many decades ago I noticed and began to override my knee jerk reactions to people’s personalities and belief systems. It was then I could examine my own programmed thoughts and feelings. Alcoholics Anonymous calls this as Principles before personalities.
This examination is ongoing.
