Eliminate or Adapt

Yesterday a friend called me and advised something new. She said for your special occasion you should change a little more, you should eliminate anything which is bothering you and try to not adapt with them. From the view of her theory, by discarding all the things which is making me sad or angry ,I can reach to a good level of self satisfaction and at the end reaching to internal tranquility. Of course it's a dream for all expecting mothers.
Now when I look deeper I see it's the way all the times I've tried to do. Lots of times ,I've left a place intentionally or stop a discussion by my own to change the environment. But there is a bad point in this behavior. People will call you selfish and deluded. Because they have made that situation and they think it's true so if you eliminate it ,they won't understand you at all.
I think I'm confusing you, maybe you should be in my shoes to find what I'm saying.Any how ,I won't change my manner and I'll do this behavior stronger than before until the opposite is proven.
