How do I keep going in my field as I get older in a young person's game?

You built a real career, and then the ground moved. The industry changed its shape, and now it feels built for people half your age. That is a disorienting place to stand, and grieving the game you knew is fair. But being older in a young person's field is not only a loss. You are carrying something the young ones do not have yet. You have decades of experience, of craft, of knowing what lasts and what is just noise. The tools and platforms change, but taste, skill, and judgment do not go out of style. Your job is not to out-young the young. It is to find where your particular depth is still wanted, and to be willing to learn the new tools without pretending to be new yourself. Think about what only someone with your years can offer. Teaching, producing, mentoring, a kind of work that values seasoning over novelty. The field changed, so change your place in it rather than trying to win the same race you did at twenty-five. Age is not the end of your usefulness in music. It is a chance to trade the sprint for something that lasts longer.
