I am not Einstein but in my 40s and definitely doing a lot with my time: on one side it was hard commitment and fierce hustling for 15-20 years in the past, on the other side hustling increases efficiency and high-level productivity dramatically, so that I can now do a lot (and well conceived / designed) in a very short time. Low-level implementation is invariantly slower though, be it by yourself or delegating. As an analogy with more talented people, I suspect scientists finding their Eureka! moments easier worked very hard for a long period in their past.
