When I was a child my dad told me that I had to spend time with people who were better than me in a certain skill. In my case as I am a musician, I always told myself that I had to spend time with musicians who were better than me, because that way I can advance in my things and I can also learn other positive things.
It's like that saying of Tell me who you're with and I'll tell you who you are.
Exact... "Tell me who you're with and I'll tell you who you are."
