How do you find real friends after your thirties?

After your thirties, between your job, your commute and taking care of yourself, how on earth do you find the time or the way to create meaningful, deep and lasting friendships and relationships?

Someone tell me please. The only thing I can think of is hobby communities.

P.S.: I've been in a sports community for 10 years and it has helped me nothing. Everyone just went straight home after training and no one gave a sh*t to even come talk to me to hang out. I've also been able to forge some decent friendships out of online people but they've been fizzling out.
