I'm 36 and in a similar boat. Without going into my story, I'll tell you that one thing that has been helpful for me is "giving back."
For instance, like you, I used to enjoy music festivals (still do, but differently now). Remember how cool your first festival was? How can you contribute to the experience that the first-time 20-something festival goers have now? Build a cool piece of LED art? Volunteer? Start on a project. Get involved.
The above is just one example of the many ways I've found to give back in various areas of my life. It is fun, rewarding, and opens doors to new opportunities and people.
