It's very challenging, but at the same time, much more fulfilling. I find myself more focused and therefore more efficient with my time. I learn but don't spend time going down rabbit holes. I ponder philosophy as I play with my children, and I often learn so much from them. And, their bed time is 2-3 hours before mine, so naturally I'm able to spend quality time with my wife, enjoy a hobby (I'm a guitarist, thinking of picking up piano), or get in some extra work or side projects.
