1. First of all, you stop caring what other people say to you or about you, good or bad. Never depend your happiness and well-being on other people. 60 percent of the times, people think about themselves(my problems, my goals, etv)! 30 percent is relationships, but how it affects THEM! 10 percent is empathy( How does Lisa feel? etc) As you see, people are very into themselves. So don't bother to seek approval from anyone.

2. Get to know yourself. Who are you? What do you live for? Why are you here on earth? When you find out, LIVE FOR THIS PURPOSE/DREAM/GOAL. This will bring a lot of joy into your life.

3. Did I mention that people are self absorbed?
