You're always choosing the most pleasurable thing and getting away from the most painful thing.

But sometimes you choose some painful things. How can that be?

It's because of your belief system. You believe that some things that are bad for you are actually desirable.

So, you cut yourself, you drink alcohol, you smoke cigarettes, you harm others.

That's the paradox. Some belief systems that you have doesn't actually serve you.

Get rid of them.
