Some say they think with their own head (right) and do not let themselves be influenced (wrong).
We are all constantly influenced by everything around us and no one is immune to it.
“Tell me who your friends are, I’ll tell you who you are.”
If you want to be a footballer, you can not choose to spend most of your time with friends drinking beer.
If you want to succeed at work, you can not hang out with losers who spend the time complaining but do not solve anything.
If you want to be a cook, you can not have most of your conversations with the cobbler, but with a chef.
