35m not married and no kids. What are some things i should be working towards?

I'm pretty set on not having kids at this point. I'm making ok money, enough to live on my own relatively comfortably in Sacramento, Ca. I have some hobbies, DnD, Lego, theater. I'm in a union job and work matches my 6% investment to my retirement fund. Workout semi regularly. What are some things i should be putting my focus on to better myself?
