It happens sometime between a man's late teens and mid-30s. It's the recognition that you do have a responsibility. That image matters, challenge is good, individuality isn't about some false sense of instant gratification, and pursuit of success means progressing agendas and being your brother's keeper. It's knowing you can have as much fun in full acknowledgment as you did in blissful ignorance. Even more so. Because growing up while staying young isn't some juxtapose or oxymoron. It's a life lived to capacity. Just ask Jay.
