Anything you missed out on when you were younger and now it feels too late?

Title says it all.

I never got to go to concerts or music gigs when I was younger at all (could never afford the tickets)

Now I'm 30 I just feel too old to go to my first concert, like it just feels off, like that ship has sailed.

Anyone else had something similar, where you missed out when you younger and now it feel too late to really enjoy it?
