I had another new hire start today. Hiring is a terrible, soul-sucking process that has no shortcuts, but when you do get it right, it's like magic. I've said it a hundred times that much of success is just surrounding yourself with awesome people.
Art has a funny way of giving you focus and making you think. A number of songs, movies and plays and musicals that I've seen lately have drawn attention to the fact that your impact on the world is often measured in your interaction with others, and not necessarily by the things you create. So combined with hiring and otherwise mentoring my existing team, it kind of gives me a charge to think about it. I know from experience how important this is. Even before I had any professional momentum, I could see the impact that coaching teenagers had (and hopefully that impact went beyond better high school seasons).
You have to invest in people. Yes, it's very possible that you could turn mediocre people into great people, and then they'll leave. But what if you let them be mediocre and they stay?
