The future is something that very few of us have an accurate idea of how it is going to be. Even among those whose ideas of the future turns out to be accurate, a lot of luck is usually involved.
One of the problems is that a lot of our thinking is biased by what we have experienced in the past. We naturally assume that our future is going to be similar to our past.
This is a bias one has to overcome. Being aware of this bias will help with reducing any arrogance one might have about knowing too much, while the reality is that we know very little. As Socrates is supposed to have said:
“The only thing I know, is that I know nothing”
