You will become the people who you surround yourself with.
Hang out with drug addicts and you will become addicted too. Hang out with guys who cheat on their wives and sooner or later you will do the same.
Surround yourself with smart people who strive to better their lives, and you will become that person too.
Think about anybody you know and about who his or her friends are. It makes sense. You hang out with people who do things that you like and it is likely that you do the things that you like.
Now think about not only your friends, but also what kind of YouTube channels you watch regularly, what kind of books you read, and whom you follow on Twitter.
Do you want to become these people? Because you are.
