As others, I 100% agree with this and it's what I've also been focusing on as a manager.

Someone told me: Once you have 10 people on your team, if you spend 100% time coding, you increase amount of coding by 10%.

Instead, either spend time finding that next hire (increase by 10%), or work on other things that improves the team's productivity even more.

For me, the hard part is when the team size is ~5-8 people. Too big for me to be 80% technical, but usually not quite such that managing is 80% either. This is when it's easy to sign up for critical tasks and get interrupted due to manager stuff, and as a result work 160% total. Once the team grows it usually gets easier.
