Amateur astronomy and astrophotography. I honestly look forward to finishing a long, tough day of whatever just to come home to my telescopes, have silent thought-conversations with all the beautiful objects in the sky. The moon is so much more beautiful when you've seen her up close, and no matter how many times I've seen it I still flip out every time my eyepiece finds Saturn. It's so worth the sleep deprivation lol, just really adds to my quality of life and it's really humbling too. Gives you an interesting perspective of your significance and how inconsequential many of your problems really are.
