Understanding Things

There are some things in life that we will not understand until much later. there are other things that we will never understand.

No one can say which things are which because there is a third category of things - those that we may be able to understand - but which are adept at eluding our understanding. It may take research and hard work to understand this third category of things. It may also take much time.

Finally, there is a fourth category of things that is even more troublesome. These are the things which can be understood, but which are ultimately able to evade our understanding them no matter how much work or time we put into it.

How much work then should we apply to understanding? How do we assess the value of understanding and prioritize it based on the likely ROI?
