You will change over the months and years. This we know. But how you will change depends on your future environment, the mind food you feed yourself.
Conversation is a big part of our psychological environment. Some conversation is healthy. It encourages you. It makes you feel like you're taking a walk in the warm sunshine of a spring day. Some conversation makes you feel like a winner.
But other conversations are more like walking through a poisonous, radioactive cloud. It chokes you. It makes you feel ill. It turns you into a loser.
Go first class: that is an excellent rule to follow in everything you do.
