This is an episode about the late great Mr Jung i'v heard how influential a guy he was i haven't ever read his knowledge before so this should be interesting. The quotes i talk about are below for you to refer back to if you like:

Even a happy life cannot be without a measure of darkness, and the word ‘happy’ would lose its meaning if it were not balanced by sadness.

The meeting of two personalities is like the contact of two chemical substances: if there is any reaction, both are transformed.

The shoe that fits one person pinches another; there is no recipe for living that suits all cases.

The least of things with a meaning is worth more in life than the greatest of things without it.
