Here are some examples from my never ending list:
Cozy nights with my family
Watching my husband play (or coach) soccer
My daughter's giggle
Listening to her read
Making art with kids (of all ages!)
Soldering anything that stands still
That good feeling you get in your heart when a kid says 'I love you'
The color blue
The smell of funky old book stores
Fierce artists - of all ages!
