When All You've Ever Wanted Isn't Enough: The Search for a Life That Matters (ISBN 0-7432-3473-1) is a 1986 book by Harold Kushner, a Conservative rabbi.

Kushner addresses in the book matters of existentialism, particularly the meaning of life and the individual pursuit of happiness.

Kusher explained that he aimed to explore why individuals who achieve success may not feel fulfilled with their lives.

Kushner argues that readers can learn from Ecclesiastes that life is its own reward, that death is less fearful than never having lived, and that the worst hell is realizing that one could have been a better human being but never made the effort.

[2] It also drew insights from modern thinkers like psychologist Carl Jung, author Johann Wolfgang von Goethe, and philosophers Jean-Paul Sartre and Martin Buber.
