Yes. I am quiet opinionated, so I can see how I would come off as seeming proud. It was more a problem for me when I was younger, but I've mellowed as I've got older and realised that everything isn't as black and white as I used to think it was.
I think what has helped me is the different people I've met over the years and how listening to them and trying to understand their perspective on life has changed how I view things.
Although, alot of the time I do think I'm right, but I just keep my mouth shut. I used to argue points to the death, but I don't bother now. I think that makes me easier to get along with in real life.
