I've been going a mindfulness/meditation class once per week for a while, and downloaded a "mindfulness bell" app to my phone, which reminds me periodically throughout the day with a chime to stop, breathe, maybe stretch (whatever I think appropriate).
I generally read a book every day on my lunch break for about 15 minutes, sometimes fiction, sometimes non-fiction. I go to all the parenting lectures/get togethers at my son's preschool, and try to at least skim parenting books to try to improve myself.
I often read something short and inspirational right before bed.
I spend time holding DH's hand or snuggling with him on the couch a couple times per week if possible. He is often gone in the evening, so it's really important to me to reconnect with him as much as I can.
The one thing I wish I could just turn off would be yelling. I haven't conquered that. But getting enough sleep and practicing mindfulness help decrease it to some extent.
