To be frank, if you are like me, you could improve how you deal with disagreements. We all could.
It is not easy to have someone disagree with our careful thoughts, but it is a precious skill nonetheless.
I noticed that I tend to think that people who disagree with me to be stupid and annoying. What I realized is that in most cases they are not.
In most cases, they just disagree with me.
Learning to separate these two things brings a huge improvement in life quality. I am not there yet but I keep trying.
