"In life you have 2 options. You can either do your own things and stand out, or do what everyone does and "fit in"' - Casey Neistat
Casey Neistat is a Youtuber who probably has the most influence on me. He was asked on one of his vlog Q&A, how to surround yourself with the right people. His answer to this question, he doesn't. He just eliminates the bad people. If there is someone he doesn't want in his life, 'Get out'.
This is something that relates to me very much. I have been unconsciously eliminating 'bad people' since the beginning of this year. I really have so much to say about this, but I probably won't be able to express myself well. Long story short, I'm a happier and more focus person without those people in my life.
