It's advice they give to working musicians. You need to be good at music, but you need to be fun more than you need to be good at music. You can be the best guitar player in your area, but if you're a drag then they'll just hire the second best guitar player, since most working musicians don't need to be the best. This is unfortunately advice along the same lines as "be attractive". It's not something that's fair, and it's not something that's universal, but generally speaking if you're fun and attractive, you'll have an easier time achieving success. That's perhaps a bummer to realise, and again not a universal truth, but for most people it's actionable advice.
