Think Big To Push The -ve

I'm reading the famous book, The Magic of Thinking Big by Dr. David Schwartz. And I I vouch for the changes that have taken place in me. This book is like a Bible for the ones who are stuck with pessimistic approach to life. The realistic examples, easy language makes it greatly readable and understandable, with so many learnings. 

One such learning I got from it is to (try) think big and positive when people surround you with negativity and try to bring you down. Follow these 4 things: 

1. When you refuse to fight petty people, in that exact moment, in that exact time, you win. Your mental health wins. 

2. Never ever take anything for granted, even the positive parts you stumble upon. 

3. People only take or pick on you because there are problems they are facing and have. Feel sorry for them. 

4. Build your immunity against such people who try eating you up. 

Cheers.
