That’s always that field of tension between focus and diversification when it comes to your time and energy. In the end it comes down to a compromise. How „big“ that is, meaning how far you decide for one direction is dependent on the projects you are working on and how convinced you are regarding their success.
I do it similar to yourself, Jon. Focus on a few projects and tasks, which is not laying all eggs in ONE basket but also not spraying your energy around.
