Someone on here pointed out that adults lament the loss of the creativity of our childhood, but we lost it because we're tired and stressed out all the time.
I could contribute more to the world GMing TTRPGS, or learning to write poetry, or any of a long list of silly projects, rather than sitting at work logging in and out of things and watching progress bars and copying serial numbers into spreadsheets and generally not being able to concentrate on anything for more than a few minutes.
