If we can understand that we control nothing in this world, not the country, not your school, not your classmates, not your friends and enemies (if you even prefer to see people as enemies), not your family, not your siblings, and not even your own thoughts (now don't think of an apple. did you think of an apple?) and body (you can't control when you want to get sick and when you want to get better right?),

We would be much more content on this world.
