Humility is also an important element for rebooting one’s career.
It should be noted that having confidence in yourself is not mutually exclusive to humility. One aspect of humility is to accept the fact that you don’t know everything on earth and other people sometimes (not always :>) may also have valid points that you can learn from.
I think often time humility may be impaired when we become more advanced in age and experience. A balance should be struck between having confidence in our experience and humility.
