I don't believe that you remain uninfluenced as you are surrounded by influences, even if they're subtle. The internet, news and media, books, TV and movies, marketing, school teachers, behaviours you are exposed to on the street and from strangers, thoughts and opinions you overhear, parents and family...so many more things, and not just people, influence everyone on the planet to some degree...even this post you just read.
It's good that you feel you've been a good influence on others, I wonder if others would say the same? Let's hope.
You are right, we are constantly being influenced.
Maybe I did not express myself correctly or the translation was not the best.
I meant that I am not easily influenced. I always weigh the pros and cons before making decisions.
I think the ability to weigh things up, practically apply them to life, present and future, is a valuable skill and one that means a person might have a better chance to hold off bad influences and move forward in better ways. Well done.
