When it comes to hiring, always hold out for the right person. 

Play the long game. Don't hire someone who is not the right person just so you can fill a position. 

If you don't have great people you won't become a great organization. Being excellent is hard. And you need the right people to be excellent. 

Sure, it can become frustrating to deal with the extra work that comes from an empty position. But hiring the wrong person will create even more work.
