Journey without it and you will never prevail, but if you have too much of it you will surely fail.

Why this works

This riddle plays on the dual nature of confidence in achieving success. The first part, "Journey without it and you will never prevail," highlights that a certain level of confidence is essential for taking risks and pursuing goals; without it, one might hesitate or give up too easily. Conversely, the second part, "but if you have too much of it you will surely fail," warns that excessive confidence can lead to overestimating one's abilities, resulting in poor decisions and potential failure. Thus, the riddle cleverly captures the delicate balance needed to navigate challenges successfully.
