Walking my dogs, playing with my kids - all of that is really good stuff to keep me centered.
As an artist and a songwriter myself, I like to feel connected to modern culture and watch how sounds change. 
How do I not get so wrapped up in what I think needs to happen? Going with the flow is the way to do it.
I do pranayama breathing now as a meditation, and that's very helpful. Meditating changed my life.
I pray to the architect that designed me. I'm grateful.
Whether I'm stressed out or angry or happy or depressed - however I feel, I say "I love my life," no matter what. That usually keeps me centered. 
Yoga really helped with stress relief and just not hurting myself when I tour. It really was super helpful.
