Sure, learning changes you. Some of that learning is deliberate and some is unconscious, and you are what you learn. I don't think it means you should be afraid to learn new things, but you might want to pay attention to what you spend your time learning.
Aagree. I mean we can't avoid being influenced or be afraid of learning new things. That's impossible anyway.
I think what I'm getting at is being a little more conscious of what we're consuming and how much of our preferences/behaviour we're adopting unconsciously.
