You are who you surround yourself with

Yes... to a degree this can be true.

If you are a person who is easily "influenced" then yes, you can totally become or morph into the "person or crowd" you are hanging out with. Good or Bad~

However, if you are a Strong-minded person, with a good moral compass & know your true self, then no amount of influence will change the person that you are inside.
