- Started working out 1-2 hours per day (trail hiking/running)
- Stopped reading my iPhone in bed at night, now I just read my backlit Kindle
- Company switched to all-remote (used to commute to SF)
- Had a daughter (~9 months old now, so not coincident with the sleep switch)
- Almost all of my job responsibilities are management now (previously I was still doing more IC-like work)
- Cut down on sugar intake
If you asked me 3 months ago, I would have sworn I'd be a night owl for the rest of my life. So, this is quite a (pleasant) shock to me. Posting this in case it's helpful to anyone who's a night owl and thinks it's impossible for anyone to switch.
