My work/life balance sucks.
I plan my weekends off like you'd normally plan vacations because they occur with roughly the same frequency. I don't get to see my family or friends nearly as much as I'd like and when I do it's often in a very timeboxed fashion that doesn't leave enough room for serendipity. I've seen our coworking space at all hours of the day and night and share a special connection with the handful of others who regularly do the same. I have a growing list of hobbies and events that I want to do or try that never gets any shorter. I suck at spontaneity now. I started booking meetings 5 minutes shorter just so I'd have time to run to the restroom or grab a bite between them.
This typically looks like a recipe for a painfully sad existence.
I've never felt more stimulated or alive.
