Instead of searching for our passion, he suggests that we should focus on building up our capability (he calls it "career capital") by capitalising on every opportunity.

In the end, we are taking many small bets on our lives and hopefully, the big break will come.
Mike Rowe also shared his experiences on why he think the happiest people are not the one who followed their passions.
