Here are some quotes from Erich Fromm, a classic self-analyser.
"One cannot be deeply responsive to the world without being saddened very often."
Or in other words; those with experience of having less gain more pleasure from a normal existence.
"Both dreams and myths are important communications from ourselves to ourselves. If we do not understand the language in which they are written, we miss a great deal of what we know and tell ourselves in those hours when we are not busy manipulating the outside world."
C'est bon!
"Care and responsibility are constituent elements of love, but without respect for and knowledge of the beloved person, love deteriorates into domination and possessiveness."
Rather an oversimplification but a good philosophy to live by.
"Man's main task in life is to give birth to himself, to become what he potentially is. The most important product of his effort is his own personality."
A curious circle of analysis. Everyone produces their own personality! Also the tenses are wrong, you can potentially "be". If you "are" then your potential is realised. States vary. Opinions of potential vary. I think this quote makes little sense, it might be more worthwhile to say that one should improve oneself, although what is improvement is a matter of opinion. I think he meant that a goal makes one happier; enough said.
"Creativity requires the courage to let go of certainties."
Courage has nothing to do with it! If you only do what is certain you are indeed not being creative. Creativity is revolution. That's a better way of saying it.
