What's soul crushing? Meaningless senseless acts? Being quiet when you want to scream? Feeling like you're a small unimportant cog in a vast machine that doesn't care about you?
What's the opposite of soul crushing? Working on something you love and then putting it out there and finding that a lot of people adore it? Finding what you create has value?
I suppose the opposite of soul crushing would be soul uplifting. It seems to be in short supply these days.
