You don't stay sharp across the entire discipline, that's the trade off. Inherently a generalist will always be behind a specialist. As someone in a similar spot. I've found that two practices keep me effective. 1. Stay on the '80' side of the 80/20 rule. Find breakpoints where you are getting diminishing returns. Stop yourself when you are getting into specialist territory, by asking 'how often am I going to need this?' 2. Have a network of specialists who you can call when you need abilities in that last 20%. This is the hardest part because you will have made a lot of progress and want to just keep going on your own. It's important to take a step back and think "I could call <specialist> and they would knock this down in a day". As a generalist think of yourself as consumer rather than a producer.
