10. Set an alarm for whatever time your workday ends and stick to it
Our team was made up of 8 people and we all worked remote. We all had the problem of starting work between 8-9 and finding that we were still working come 9PM.
For me, it was easy to loose track of time and not even realize how late it was. Setting an alarm for 5pm and leaving my office when it went off was key to a healthy work/life balance.
This doesn't mean you never work late. It just means you are purposeful about it. Sometimes I would "snooze" my alarm for a few extra minutes, or set a new one for an hour later if we really needed to meet a deadline.
