The life crisis.
What is the life crisis? The quarter-life crisis, the midlife crisis, among others.
When does this crisis occur?
Who does it happen to? Why do some people not have one, while others have them multiple times a day?
What spurs this crisis? The accomplishments of others? Our own recognizition or our unsatisfactory progress in life?
Might these crises be constructive in our personal development?
Perhaps I have more questions than answers here, but all questions deserving of attention.
