For a variety of information on Jung's life, writings, and the thoughts of others on Jung, see any of these sites:

In addition to these sources of information, here is, in a nut shell, Jung's major concerns. In simple terms, Jung sought to:

Encourage us to stop always looking outward and to spend a portion of our daily lives looking inward.

Help us to realize that our inner experiences are "real".

Help us realize that our psyche is very broad and deep.

Help us to open ourselves to the unknown and mysterious inner world.

Help us realize our complexity (e.g. to see our many sides).

Help us appreciate myth and symbol since they tend to move us closer to our inner world.

Help us realize that the psyche is an autonomous force in our lives, capable of leading us mentally and physically.

Help us to find a solid, seemingly incorruptiable center which organizes the psyche (the Self).
