For 20 years I’ve been hiring and firing people.
For the most part, if you hire the smartest ones of the bunch, you’ll have more good performers than bad performers. That means pure intelligence, not necessarily book smarts.
Just hiring smart people still isn’t the answer. You want to hire good, or great, people every single time. How do you do that? That’s the million-dollar question.
There is one trait we don’t focus enough on, across all industries: optimism. Your best employees almost always have a level of optimism that your lower performers don’t.
They might be optimistic about their future, about the company’s future, about life in general.
