For in much wisdom is much grief,
And he who increases knowledge increases sorrow.
Ecclesiastes 1:18
I kind of agree with this! The more one knows the more aware that more is left to know and a lifetime is just not enough to learn even if we could afford to spend the entire life with learning. Wouldn't that be great?
But we need to toil (aka work!). So, since the time for learning is cut short by the time for working the only option is to accept we are pretty dumb.
And because thinking that one is pretty dumb is not really helping feel good about oneself, then better to just don't even think about and accept that I know something.
In the end is just a matter of do I see the glass half full or half empty.
The interesting comes when I meet some people who by looking at their half filled glass, they boast that their glass is full. That is a pretty high self-esteem (value that one places on personal abilities and worth). However, we know that is good to have a high self-esteem, but not too high; or at least not much higher than the self-efficacy (perception of how successful one's abilities are to perform a certain task).
Think about the peacock, now that is a bird that has a high self-esteem and pretty much showing it.
There are among us some "peacock" individuals who show off with their skills or knowledge, or possessions.
Now their glass is overflowing!
Which brings me to the conclusion that much knowledge makes us better evaluate how less we know.
Then still remain the two options: be sad for knowing so less, or accept that you know a little
