Much of your suffering is caused by having strong opinions. Opinions cause you to become defensive and judgemental. They keep you trapped in a state of conflict with others.
Here's the magic formula of liberation:
If you aren't an [economist, politician, theologian, doctor, scientist], the world doesn't need your opinions about [economics, politics, theology, medicine, science].
Just be a decent, loving person and stop working overtime trying to do other people's jobs.
