We are many human beings in this world. We are in groups according to what we think about life. It's in accordance to what we think and what we believe in as people. Sometimes it requires another person to make you believe in what they believe in. But everyone has their own theory about life basing on what they experience in life. Since we experience things in life differently, our view of life tends to be different. Life experiences can be positive or negative basing on which part of life it is, "love, friends, work, money". What I can tell you is that life is one big fight. You are you, and what someone says about life let it not change you negatively unless it's positive because we don't experience life the same way. That's why it's good to be close to people who are positive with life otherwise you may end up failing in life with negatively attituded people.
All in all love God.
