[General smart superheros] How do people like Batman and Sherlock Holmes manage their time?

I don’t know the comics, but from what I have heard, Batman constantly prepares for all contingencies and also keeps himself physically fit as well as informed about all kinds of topics. Ozymandias is similar. Sherlock Holmes is famous for conveniently knowing about very fringe subjects that are useful for his trade.

How do these people manage to do all of this? Do they use apps to keep track of all the recent developments in areas that are useful for them? How did they acquire such knowledge in the first place? How do they train their skills to have them ready when needed?

As for Sherlock Holmes, I cannot recall any mentions of him using a rigorous time schedule in between cases to update and extend his knowledge and skills, except in chemistry. For Batman I have heard it mentioned that he spends most of his spare time working out and planning. So this at least would fit the skills that he is shown to possess. But is ist ever mentioned how he organises all of these tasks needed for keeping on top of the game?

Sherlock Holmes in the books makes way more sense.  Holmes cares about one thing, and that's being the best detective.  So he EXCLUSIVELY reads about things that will make him a better detective.  He's essentially the first min-maxer in fiction.  

If you pick a topic of discussion that doesn't include the niche things Holmes is an expert on, he'll appear to be quite stupid since he devotes zero time to anything not related to being a detective.
