I was wondering how a normal adult in their 20s could best structure their life to make best use of their capacity to learn. (I am no expert in cognitive science, so I assume just a really common definition of "learn" here. We might measure this by, for example, hours of sustained, intense study per 24 hrs. I realize my question might be a major oversimplification also, leaving out factors like stress.).
If there is some upper bound on how quickly learning occurs, then there may be little point in e.g. studying > 6 hrs. per day. Does anyone know of any research which shows some general, asymptotic upper bound for learning in adults (20-30)?
Anectodal examples might also be useful, so what are some examples of the "most learned" adults and how they structure their days?
