There was an interesting thing emerged from database theory about 15 years ago:
That for a fully loaded processor, the most efficient possible search algorithm is the fully random search.
If you are really busy, be as random as possible in your interests.
And you need to accept before you start that the world is far too large and complex to even perceive everything in it, let alone understand. And one can make reasonable approximations to survey most of the general classes and at least make a start at investigating most of the interpretive schema available. Which is pretty much what I have been doing for the last 50 years. Should I live for the next 10,000 years I think I will still be finding new and interesting things to explore about this planet.
The universe seems sufficiently complex to occupy the rest of eternity (and considering the trajectories of evolution at present, it is entirely possible that this planet alone could keep one interested for the rest of eternity).
